| 1 | Antimony(V) removal from water by hydrated ferric oxides supported by calcite sand and polymeric anion exchanger显示文摘We fabricated and characterized two hybrid adsorbents originated from hydrated ferric oxides(HFOs) using a polymeric anion exchanger D201 and calcite as host. The resultant adsorbents(denoted as HFO-201 and IOCCS) were employed for Sb(V) removal from water. Increasing solution pH from 3 to 9 apparently weakened Sb(V) removal by both composites, while increasing temperature from 293 to 313 K only improved Sb(V) uptake by IOCCS. HFO-201 exhibited much higher capacity for Sb(V) than for IOCCS in the absence of other anions in solution. Increasing ionic strength from 0.01 to 0.1 mol/L NaNO3would result in a significant drop of the capacity of HFO-201 in the studied pH ranges; however, negligible effect was observed for IOCCS under similar conditions. Similarly, the competing chloride and sulfate pose more negative effect on Sb(V) adsorption by HFO-201 than by IOCCS, and the presence of silicate greatly decreased their adsorption simultaneously, while calcium ions were found to promote the adsorption of both adsorbents. XPS analysis further demonstrated that preferable Sb(V) adsorption by both hybrids was attributed to the inner sphere complexation of Sb(V) and HFO, and Ca(II) induced adsorption enhancement possibly resulted from the formation of HFO-Ca-Sb complexes. Column adsorption runs proved that Sb(V) in the synthetic water could be effectively removed from 30 μg/L to below 5 μg/L(the drinking water standard regulated by China), and the effective treatable volume of IOCCS was around 6 times as that of HFO-201, implying that HFO coatings onto calcite might be a more effective approach than immobilization inside D201. | Yangyang Miao Feichao Han Bingcai Pan Yingjie Niu Guangze Nie Lu Lv | 2014 | Journal of Environmental Sciences2014，26，2： | 20 |
| 2 | Application potential of carbon nanotubes in water treatment:A review显示文摘Water treatment is the key to coping with the conflict between people's increasing demand for water and the world-wide water shortage. Owing to their unique and tunable structural, physical, and chemical properties, carbon nanotubes (CNTs) have exhibited great potentials in water treatment. This review makes an attempt to provide an overview of potential solutions to various environmental challenges by using CNTs as adsorbents, catalysts or catalyst support, membranes, and electrodes. The merits of incorporating CNT to conventional water-treatment material are emphasized, and the remaining challenges are discussed. | Xitong Liu Mengshu Wang Shujuan Zhang Bingcai Pan | 2013 | Journal of Environmental Sciences2013，25，7： | 15 |
| 3 | Enhanced debromination of 4-bromophenol by the UV/sulfite process:Efficiency and mechanism显示文摘Halogenated aromatic compounds have attracted increasing concerns due to their toxicity and persistency in the environment, and dehalogenation is one of the promising treatment and detoxification methods. Herein, we systematically studied the debromination efficiency and mechanism of para-bromophenol(4-BP) by a recently developed UV/sulfite process. 4-BP underwent rapid degradation with the kinetics accelerated with the increasing sulfite concentration, pH(6.1–10) and temperature, whereas inhibited by dissolved oxygen and organic solvents. The apparent activation energy was estimated to be 27.8 kJ/mol. The degradation mechanism and pathways of 4-BP were explored by employing N_2O and nitrate as the electron scavengers and liquid chromatography/mass spectrometry to identify the intermediates. 4-BP degradation proceeded via at least two pathways including direct photolysis and hydrated electron-induced debromination. The contributions of both pathways were distinguished by quantifying the quantum yields of 4-BP via direct photolysis and hydrated electron production in the system. 4-BP could be readily completely debrominated with all the substituted Br released as Br-, and the degradation pathways were also proposed. This study would shed new light on the efficient dehalogenation of brominated aromatics by using the UV/sulfite process. | Bihuang Xie Xuchun Li Xianfeng Huang Zhe Xu Weiming Zhang Bingcai Pan | 2017 | Journal of Environmental Sciences2017，29，4： | 12 |
| 4 | Preparation of polymer-supported hydrated ferric oxide based on Donnan membrane effect and its application for arsenic removal显示文摘In the present study a novel technique was proposed to prepare a polymer-supported hydrated ferric oxide (D201-HFO) based on Donnan membrane effect by using a strongly basic anion exchanger D201 as the host material and FeCl3-HCl-NaCl solution as the reaction environment. D201-HFO was found to exhibit higher capacity for arsenic removal than a commercial sorbent Purolite ArsenX. Furthermore, it presents favorable adsorption selectivity for arsenic removal from aqueous solution, as well as satis- factory kinetics. Fixed-bed column experiments showed that arsenic sorption on D201-HFO could re- sult in concentration of this toxic metalloid element below 10 μg/L, which was the new maximum con- centration limit set recently by the European Commission and imposed by the US EPA and China. Also, the spent D201-HFO is amenable to efficient regeneration by NaOH-NaCl solution. | ZHANG QingJian PAN BingCai CHEN XinQing ZHANG WeiMing PAN BingJun ZHANG QuanXing L.LV X.S.ZHAO | 2008 | Science China Chemistry2008，51，4： | 4 |
| 5 | A settling curve modeling method for quantitative description of the dispersion stability of carbon nanotubes in aquatic environments显示文摘Understanding the aggregation and deposition behavior of carbon nanotubes(CNTs) is of great significance in terms of their fate and transport in the environment. Attachment efficiency is a widely used index for well-dispersed CNT solutions. However, in natural waters, CNTs are usually heterogeneous in particle size. The attachment efficiency method is not applicable to such systems. Describing the dispersion stability of CNTs in natural aquatic systems is still a challenge. In this work, a settling curve modeling(SCM) method was developed for the description of the aggregation and deposition behavior of CNTs in aqueous solutions. The effects of water chemistry(natural organic matter, p H, and ionic strength) on the aggregation and deposition behavior of pristine and surface-functionalized multi-walled carbon nanotubes(MWCNTs) were systematically studied to evaluate the reliability of the SCM method. The results showed that, as compared to particle size and optical density, the centrifugal sedimentation rate constant(ks) from the settling curve profile is a practical, useful and reliable index for the description of heterogeneous CNT suspensions. The SCM method was successfully applied to MWCNT in three natural waters.The constituents in water, especially organic matter, determine the dispersion stability of MWCNTs in natural water bodies. | Lixia Zhou Dunxue Zhu Shujuan Zhang Bingcai Pan | 2015 | Journal of Environmental Sciences2015，27，3： | 4 |

| 9 | Recyclable polymer-based nano-hydrous manganese dioxide for highly efficient Tl(I) removal from water显示文摘Tl(I)in water even at a trace level is fatal to human beings and the ecosystem.Here we fabricated a new polymer-supported nanocomposite(HMO-001)for efficient Tl(I)removal by encapsulating nanosized hydrous manganese dioxide(HMO)within a polystyrene cation exchanger(D-001).The resultant HMO-001 exhibited more preferable removal of Tl(I)than D-001 and IRC-748,an iminodiacetic chelating polymer,particularly in the presence of competing Ca(II)ions at greater levels in solution.Such preference was ascribed to the Donnan membrane effect caused by D-001 as well as the specific interaction between Tl(I)and HMO.The adsorbed Tl(I)was partially oxidized into insoluble Tl(III)by HMO at acidic pH,while negligible oxidation was observed at circumneutral pH.The exhausted HMO-001 was amenable to efficient regeneration by binary NaOH-NaClO solution for at least 10-cycle batch runs without any significant capacity loss.Fixed-bed column test of Tl(I)-contained industrial effluent and natural water further validated that Tl(I)retention on HMO-001 resulted in a conspicuous concentration drop from 1.3 mg/L to a value lower than 0.14 mg/L(maximum concentration level for industrial effluent regulated by US EPA)and from 1–4?g/L to a value lower than 0.1?g/L(drinking water standard regulated by China Health Ministry),respectively. | PAN BingCai WAN ShunLi ZHANG ShuJuan GUO QingWei XU ZhengCheng LV Lu ZHANG WeiMing | 2014 | Science China Chemistry2014，57，5： | 2 |

| 11 | Weakly hydrophobic nanoconfinement by graphene aerogels greatly enhances the reactivity and ambient stability of reactivity of MIL-101-Fe in Fenton-like reaction显示文摘In the pursuit of heterogeneous catalysts with high reactivity,metal organic framework(MOF)nanomaterials have received tremendous attentions.However,many MOF catalysts especially Fe-based MOFs need to be utilized immediately after synthesis or being activated using high temperature,because of the easy loss of reactivity in humid environments resulting from the occupation of active Fe sites by water molecules.Here,we describe an inspiring strategy of growing MIL-101-Fe nanoparticles inside the three-dimensional confined space of graphene aerogel(GA),generating shapeable GA/MIL-101-Fe nanocomposite convenient for practical use.Compared to MIL-101-Fe,GA/MIL-101-Fe as catalyst demonstrates much higher reactivity in Fenton-like reaction,attributing to smaller MIL-101-Fe particle size,presence of active Fe(II)sites,and abundant defects in GA.Strikingly,the weakly hydrophobic nature of the composite greatly inhibits the loss of catalytic reactivity after being stored in humid air and accelerates the recovery of reactivity in mild temperature,by resisting the entrance of water molecules and helping to exclude water molecules.This work demonstrates that a delicate design of nanocomposite structure could not only improve the reactivity of the catalytic component,but also overcome its intrinsic drawback by taking advantage of the properties of host.We hope this functional nanoconfinement strategy could be extended to more scenarios in other fields. | Yuwei Zhang Fei Liu Zhichao Yang Jieshu Qian Bingcai Pan | 2021 | Nano Research2021，14，7： | 2 |
