| 1 | North Qinling Paleozoic granite associations and their variation in space and time: Implications for orogenic processes in the orogens of central China显示文摘Integrated zircon U-Pb dating and whole rock geochemical analyses have been carried out for two typical S-and I-type granitoids in the north Qinling. Zircon dating by SIMS of the Piaochi S-type grani- toids yields an emplacement age of 495±6 Ma. The granitoids show whole-rock εNd(t)=-8.2--8.8, zircon εHf(t)=-6―-39. The Huichizi I-type granitoids have emplacement ages of 421±27 Ma and 434±7 Ma es- tablished by LA-ICP-MS and SIMS methods, respectively. Their whole-rock εNd(t)=-0.9-0.9 and zircon εHf(t)=-11-8.4. Combined with statistical analyses of 28 zircon ages of granitoid plutons collected from the literature, Paleozoic magmatism in the north Qinling can be divided into three stages. The first-stage magmatism (~505-470 Ma) mainly occurred in the east part of the north Qinling and has features of an I-type arc, associated with which are S-type granitoids such as Piaochi pluton. The early granitoids (~505-490 Ma) have close spatio-temporal relations to ultra-high-pressure (UHP) rocks, and thus are interpreted as an oceanic subduction system along a continental margin. The second-stage magmatism (~450-422 Ma) occured through the whole north Qinling, and is characterized by I-type granitoids represented by the Huichizi pluton. The magma is interpreted as partial melting of lower crust mixed by mantle-derived magma in a collisional setting with the uplift of terranes. The third-stage magmatism (~415-400 Ma) is dominated by I-type granitoids and only took place in the middle part of the north Qinling, and is regarded as a late-stage collision. The spatial and temporal variations of the Qinling Paleozoic magmatism reveal protracted subduction/collision. The subduction was initiated from the east part of the north Qinling, earlier than that in the Qilian-northern Qaidam, Kunlun, and northern Dabie regions. This demonstrates variations in time of subduction, accretion and collision of separate blocks or terranes in the orogenic systems in central China. | WANG Tao WANG XiaoXia TIAN Wei ZHANG ChengLi LI WuPing LI Shan | 2009 | Science China Earth Sciences2009，52，9： | 79 |

| 3 | Extraction and separation of heavy rare earths from chloride medium byα-aminophosphonic acid HEHAPP显示文摘The extraction and separation of heavy rare earths(REs) using newly synthesized a-aminophosphonic acid extractant 2-ethylhexyl-3-(2-ethylhexylamino)pentan-3-yl phosphonic acid(HEHAPP, HA) in nheptane were investigated from chloride medium. The extraction stoichiometries of lanthanum, gadolinium, yttrium and lutetium are determined to be REA3 by the slope analysis method. The favorable separation factors of adjacent heavy REs(Ⅲ),i.e. β_(Y/Ho), β_(Er/Y),β_(Tm/Er),β_(Yb/Tm) and β_(Lu/Yb), are determined to be1.87,1.36, 3.21,3.22 and 1.93, respectively, when extracted from a binary system at proper condition. The loading capacities of HA for Ho, Er, Yb and Lu increase in the order Ho < Er < Yb < Lu with the values being 0.201, 0.205, 0.216 and 0.229 mol/L, respectively. So HA would be a potential extractant for the separation of heavy REs(Ⅲ). Among inorganic acids such as H_2 SO_4, HNO_3 and HCl, HCl is tested to be the most effective stripping agent. | Shengting Kuang Zhifeng Zhang Yanling Li Haiqin Wei Wuping Liao | 2018 | Journal of Rare Earths2018，36，3： | 6 |
| 4 | Synergistic extraction of heavy rare earths by mixture of α-aminophosphonic acid HEHAMP and HEHEHP显示文摘Synergistic extraction of heavy rare earths(REs) were investigated in chloride media by the mixture of(2-ethylhexylamino)methyl phosphonic acid mono-2-ethylhexyl ester(HEHAMP) and 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester(HEHEHP). The maximum synergistic enhancement coefficients(R) of Lu, Yb, Tm, Er, Y and Ho are 2.89, 2.76, 2.54, 2.14, 2.14 and 2.06, respectively, when the mole fraction X_(HEHAMP) is 0.5. The synergistic separation factors of the heavy REs are obtained(β_(Y/Ho)=1.31,β_(Er/Y)= 1.61,β_(Tm/Er)= 1.78, β_(Yb/Tm)= 1.76, β_(Lu/Yb) = 1.20). The extracted complex is determined to be RE[H(EHAMP)_2][H(EHEHP)_2]_2 by the slope analysis method. The loading capacities of the mixtures consisting of 15% HEHAMP and 15% HEHEHP for Y and Lu are about 26.59 g/L(Yb_2 O_3) and 27.25 g/L(Lu_2 O_3),respectively. | Qi Zhao Yanling Li Shengting Kuang Zhifeng Zhang Xue Bian Wuping Liao | 2019 | Journal of Rare Earths2019，37，4： | 5 |
| 5 | A novel extractant bis(2-ethylhexyl)((2-ethylhexylamino)methyl) phosphine oxide for cerium(Ⅳ) extraction and separation from sulfate medium显示文摘By introducing the amine group into phosphorus extractant,a novel aminophosphine compound bis(2-ethylhexyl)((2-ethylhexylamino)methyl) phosphine oxide(DEHAPO,abbreviated as A) was synthesized for the extraction of cerium(Ⅳ)(Ce(Ⅳ)) from sulfate medium(H2 SO4).The influence factors including extractant concentration,H2 SO4 concentration and temperature on the Ce(Ⅳ) extraction were investigated and discussed.It is found that the extraction ability of Ce(Ⅳ),thorium(Ⅳ)(Th(Ⅳ)) and rare earths(REs(Ⅲ))(La,Gd,Yb) decreases in sulphate medium in the following order:Ce(Ⅳ)> Th(Ⅳ)> REs(Ⅲ).The extraction process is an exothermic reaction and the thermodynamic parameters were calculated.The extracted complex of Ce(HSO4)2 SO4·A in loaded organic solution was identified by the slope methods and further proved by FT-IR spectral analysis.Stripping studies indicate that Ce(IV) can be effectively stripped from the organic phase.The results of separation factors(β) and saturation loading capacity demonstrate that DEHAPO could be used to selectively extract Ce(Ⅳ) from sulphate medium with high separation efficiency and good extraction ability. | Mingxia Huang Yongmei Fu Youcai Lu Wuping Liao Zhongjun Li | 2020 | Journal of Rare Earths2020，38，12： | 3 |
| 6 | EFFECT OF BORIC ACID ON THE EXTRACTION OF BASTNASITE LEACHING LIQUOR BY CYANEX 923显示文摘The effect of boric acid on the extraction of bastnasite leaching liquor by Cyanex 923 was studied. Boric acid wasn’t extracted alone by Cyanex 923 and didn’t influence the cerium(IV) extraction. But it can enhance the extraction of hydrofluoric acid evidently and came into organic phase in form of (HF)(H3BO3).(Cyanex 923). | Liao Wuping, Li Deqian (Laboratory of Rare Earth Chemistry and Physics, Changchun Institute of Applied Chemistry Chinese Academy of Sciences, Changchun, 130022) | 2000 | 化工学报2000，51，S1： | 2 |
| 7 | Maximal methane potential of different animal manures collected in northwest region of China显示文摘Maximum methane potential(B0)is an important parameter used in assessing suitability of a substrate for biogas production.This study examined maximum methane potential of different manures generated from three major Chinese livestock,namely chicken,hog and cattle,and evaluated the important factors that affect the maximum methane potential of a substrate.The livestock manures collected from the local farms were incubated under a thermophilic anaerobic condition(55℃).The results showed that the maximum methane potential(B0)of cattle,hog and chicken manures were 292.0 mL/g VS,272.0 mL/g VS and 266.4 mL/g VS,respectively.The B0 value decreases with increasing contents of crude protein and crude fat,while increases with increasing the contents of carbohydrates and crude fiber in manures.The content of NH4+-N in chicken manure was significantly higher during the digestion period,reached as high as 1962.5 mg/L by the end of incubation period.Heavy metals of Cu and Zn in the manure also affect the B0.Empirical relationships that describe the B0 decrease in response to increase of Zn and Cu contents in manure were developed and used as a simple tool to assess the effects of these metals on the B0.It was concluded that the protein,Cu and Zn contents of manure are most important chemical compositions that negatively affect maximum methane potential.Based on the three experimental manures,the maximum methane potential was limited by either ammonium content or Cu and Zn content in the manure.For a commercial biogas production facility using these manures as main feedstock,one should consider to add co-substrate or co-substrates to reduce concentration of these chemicals to maximize biogas production. | Chen Fen Yu Gao Li Wei Liu Fenwu Zhang Wuping Bu Yushan Li Xiaomei | 2017 | International Journal of Agricultural and Biological Engineering2017，10，1： | 2 |

| 10 | Separation of trivalent rare earths from nitrate medium using solvent extraction with a novel extractant 2-ethylhexyl((2-ethylhexylamino)methyl)phosphonic acid显示文摘By introducing the amine group into the structure of P227,a novel extractant 2-ethylhexyl((2-ethylhexylamino)methyl)phosphonic acid(EEAMPA,abbreviated as HA)was synthesized for the extraction and separation of trivalent rare earths(REs)from nitrate medium.The influence factors including extractant concentration,equilibrium time,HNO_(3)concentration,separation factors,cycle regeneration,stripping acidity,and actual leach liquor of metal ions,were studied systematically.The results show that the extraction ability of EEAMPA for REs decreases with increasing acidity.A possible extraction mechanism is proposed and the extracted species as REHA_(3)(NO_(3))are confirmed by the slope analysis method.The extraction equilibrium can reach faster than P227.It shows good chemical stability and cycling regeneration.Stripping studies show that HCl is an excellent stripping agent and REs can be effectively stripped from the organic phase. | Yongmei Fu Mingxia Huang Zhulin Zhou Zhongjun Li Wuping Liao Youcai Lu | 2022 | Journal of Rare Earths2022，40，3： | 1 |

| 13 | Extraction and separation of yttrium from other rare earths in chloride medium by phosphorylcarboxylic acids显示文摘Two phosphorylcarboxylic acids,3-((bis(2-ethylhexyloxy))phosphoryl)propanoic acid(PPA) and 3-((bis(2-ethylhexyloxy))phosphoryl)-3-phenylpropanoic acid(PPPA),were synthesized for separating yttrium from other rare earths in the chloride feed of ion-adsorption type rare earth concentrate.The effect of the factors such as pH_(1/2),temperature,saponification degree and phase modifiers was investigated.The separation efficiencies of PPA and PPPA are obviously better than the typical extractants such as sec-octylphenoxy acetic acid(CA-12) and naphthenic acid(NA).The extraction process of rare earths by PPA and PPPA is a cation exchanging reaction,which is similar to those of CA-12 and NA.The loaded rare earths in both PPA and PPPA systems can be effectively back-extracted by 0.5 mol/L HCl or higher concentration.A cascade extraction process for separating yttrium from other rare earths was developed using PPPA as the extractant.The yttrium product with the purity of 97.20 wt% was obtained by 35 stages of extraction and 12 stages of scrubbing. | Guolong Wu Zhifeng Zhang Yanling Li Wuping Liao | 2022 | Journal of Rare Earths2022，40，6： | 1 |

| 15 | Extraction and Separation of Rare Earths from Nitrate Medium by Mixtures of p-Phosphorylated Calixarene and 1-Phenyl-3-methyl-4-benzoyl-pyrazalone-5显示文摘The gadolinium extraction by the mixtures of p-phosphorylated calixarene and 1-phenyl-3-methyl-4-benzoylpyrazalone-5 from nitrate medium was studied,which indicated an obvious synergistic effect between these two extractants.The extractants exhibit no interaction with each other before the metal extraction.Gadolinium(Ⅲ)was extracted by the species of Ln(PMBP)_(2)L_(2)(NO_(3))instead of Ln(PMBP)_(3)•(HPMBP)or Ln(NO_(3))_(3)•2L which are extracted by HPMBP or L alone.Thermodynamic functions(ΔG,ΔH,ΔS)were calculated.The extraction of other rare earths was also investigated and compared.Possible single rare earth separation was discussed. | Youcai Lu Yanling Li Yanfeng Bi Wuping Liao | 2014 | Chinese Journal of Chemistry2014，32，10： | 0 |
| 16 | 4.8 nm Concave {M_(72)}(M=Co,Ni,Fe) metal-organic polyhedra capped by 18 calixarenes显示文摘Three 4.8 nm isostructural{M_(72)}(M=Co^(Ⅱ) for CIAC-128,Ni^(Ⅱ) for CIAC-129,Fe^(Ⅱ) for CIAC-130) metal-organic polyhedra(MOPs) are constructed by eighteen M_(4)-p-tert-butylthiacalix[4]arene (M_(4)-TC4A) units bridged via sixteen four-connected 5,5′-(1H-1,2,4-triazole-3,5-diyl) diisophthalic acid (H_(4)TADIPA) linkers.These MOPs are featured with a rarely reported concave coordination cage,which can be simplified as a squeezed double-decker hexagonal prism pressed from the top and bottom hexagonal faces.Furthermore,CIAC-128,CIAC-129 and CIAC-130 are the highest nuclearity discrete clusters of Co,Ni and Fe reported so far.CIAC-128 has higher separation selectivity of C_(3)H_(8) than CH_(4) under ambient conditions,and also exhibits separation selectivity for C_(2)H_(6)/CH_(4),C_(2)H_(2)/CH_(4),and C_(2)H_(4)/CH_(4).In addition,CIAC-128 can provide the cavity for the confined synthesis of noble metal nanoclusters such as Pd nanoclusters and the resulting Pd@CIAC-128 hybrids show higher electrocatalytic activity than commercial Pt/C towards hydrogen evolution reaction (HER). | Haitao Han Liang Kan Ping Li Guoshuai Zhang Kaiyue Li Wuping Liao Yunling Liu Wei Chen Chunhua T.Hu | 2021 | Science China Chemistry2021，64，3： | 0 |
