| 1 | Practical performance and its efficiency of arsenic removal from groundwater using Fe-Mn binary oxide显示文摘A treatment unit packed by granular adsorbent of Fe-Mn binary oxide incorporated into diatomite (FMBO(1:1)-diatomite) was studied to remove arsenic from anaerobic groundwater without any pre-treatment or post-treatment. The raw anaerobic groundwater containing 35-45 μg/L of arsenic was collected from suburb of Beijing. Arsenic(III) constituted roughly 60%-80% of the total arsenic content. Approximately 7,000 bed volumes (ratio of efluent volume to adsorbent volume) treated water with arsenic concentration below 10 μg/L were produced in the operation period of four months. The regeneration of FMBO(1:1)-diatomite had been operated for 15 times. In the first stage, the regeneration process significantly improved the adsorption capacity of FMBO(1:1)-diatomite. With increased loading amount of Fe-Mn binary oxide, the adsorption capacity for arsenic decreased 20%-40%. Iron and manganese in anaerobic groundwater were oxidized and adsorptive filtrated by FMBO(1:1)-diatomite efficiently. The final concentrations of iron and manganese in efluents were nearly zero. The continued safe performance of the treatment units proved that adsorbent FMBO(1:1)-diatomite had high oxidation ability and exhibited strong adsorptive filtration. | Fangfang Chang Jiuhui Qu Ruiping Liu Xu Zhao Pengju Lei | 2010 | Journal of Environmental Sciences2010，22，1： | 11 |
| 2 | Development of systems for detection,early warning,and control of pipeline leakage in drinking water distribution:A case study显示文摘Water leakage in drinking water distribution systems is a serious problem for many cities and a huge challenge for water utilities.An integrated system for the detection,early warning,and control of pipeline leakage has been developed and successfully used to manage the pipeline networks in selected areas of Beijing.A method based on the geographic information system has been proposed to quickly and automatically optimize the layout of the instruments which detect leaks.Methods are also proposed to estimate the probability of each pipe segment leaking (on the basis of historic leakage data),and to assist in locating the leakage points (based on leakage signals).The district metering area (DMA) strategy is used.Guidelines and a flowchart for establishing a DMA to manage the large-scale looped networks in Beijing are proposed.These different functions have been implemented into a central software system to simplify the day-to-day use of the system.In 2007 the system detected 102 non-obvious leakages (i.e.,14.2% of the total detected in Beijing) in the selected areas,which was estimated to save a total volume of 2,385,000 m 3 of water.These results indicate the feasibility,efficiency and wider applicability of this system. | Weifeng Li Wencui Ling Suoxiang Liu Jing Zhao Ruiping Liu Qiuwen Chen Zhimin Qiang Jiuhui Qu | 2011 | Journal of Environmental Sciences2011，23，11： | 6 |
| 3 | Sn02 nanoparticles anchored on graphene oxide as advanced anode materials for high-performance lithium-ion batteries显示文摘Lithium-ion batteries (LIBs) with high energy density have attracted great attention for their wide applications in electric vehicles, and the exploration of the nextgeneration anode materials with high theoretical capacity is highly desired. In this work, Sn02 nanoparticles with the particle size of 200 nm uniformly anchored on the surface of graphene oxide (GO) was prepared by combination of the ultrasonic method and the following calcination process. The Sn02/GO composite with the weight ratio of Sn02 to GO at 4:1 exhibits excellent electrochemical performance, which originates from the synergistic effects between GO and Sn02 nanoparticles. A high discharge capacity of 492 mA·h·g^-1 can be obtained after 100 cycles at 0.2C, and after cycling at higher current densities of 1C and 2C, a discharge capacity of 641 mA·h·g^-1 can be restored when the current density goes back to 0.1C. The superior electrochemical performance and simple synthesis process make it a very promising candidate as anode materials for LIBs. | Ruiping LIU Ning ZHANG Xinyu WANG Chenhui YANG Hui CHENG Hanqing ZHAO | 2019 | Frontiers of Materials Science2019，13，2： | 4 |
| 4 | Species transformation and structure variation of fulvic acid during ozonation显示文摘The species transformation and structure variation of fulvic acid (FA) during ozonation were investi- gated in this study. The molecular weight (MW) distribution, the species of intermediate products and the variation of polar functional groups were studied by ultrafiltration, gas chromatography/mass spectrometry (GC/MS) and titration analyses respectively. The average MW of FA decreased signifi- cantly during ozonation. The amount of polar functional groups (carboxylic and phenolic (ph-OH) groups) per unit DOC (mol/kg C) increased with increasing ozonation time. Furthermore, GC/MS ex- periments demonstrated the formation of polar species (e.g., hexadecanoic acid, benzoic acid and oc- tadecanoic alcohol) and less-polar species (e.g., aliphatic hydrocarbons and butanedioic acid, bis(2-methylpropyl) ester). Electron spin resonance (ESR) measurements proved the presence of ·OH radicals in the ozonation system. Based on our experimental results, it appears that the oxidations by ozone molecule and ·OH radicals were responsible for the transformation of organics (FA and its oxi- dation products) during ozonation. These two oxidants showed significant influence on organics transformation and exhibited different mechanisms contributing to these processes. | LI Jing QU JiuHui LIU HuiJuan LIU RuiPing ZHAO Xu HOU YiNing | 2008 | Science China Chemistry2008，51，4： | 4 |

| 7 | MOF-derived Co_(9)S_(8) nano-flower cluster array modified separator towards superior lithium sulfur battery显示文摘Lithium sulfur batteries with high energy density are thought to be the most potential energy storage technology that can be commercialized.However,the shuttle effect of polysulfides deteriorates its electrochemical performance.Herein,a novel Co_(9)S_(8)nanostructure derived from metal organic framework material(MOF)was explored by simple liquid phase reaction and heat vulcanization of2-methylimidazole and Co(NO_(3))_(2)·6 H_(2)O on the surface of the original PP separator.The Co_(9)S_(8)nano-flower cluster array wall was vertically and closely arranged with the thickness of 200 nm,and the polysulfide can be adsorbed by its physical and chemical action to slow down the'shuttle effect'.It is found that the cell with the modified separator can achieve an ideal discharge capacity of about 600 mAh/g at 1 C.The specific capacity is maintained at 500 mAh/g after 200 cycles,with only 0.11%of capacity decay per cycle.It provides a new way for the utilization of MOF material derivatives to modify the separator in order to improve the electrochemical performance of lithium-sulfur batteries. | Qi Wang Hanqing Zhao Boya Li Chenhui Yang Mingyang Li Yanan Li Peng Han Miaomiao Wu Tengyu Li Ruiping Liu | 2021 | Chinese Chemical Letters2021，32，3： | 2 |

| 16 | Surface engineering for high stable lithium-rich manganese-based cathode materials显示文摘Lithium-rich manganese-based material shows great potential as the high specific cathode materials due to its low cost,environmental friendliness,high operating voltage and simple preparation process.However,the poor capacity retention and cycling performance caused by its unstable structure during cycling restrict the commercialization.In this work,Li_(1.2)Ni_(0.16)Mn_(0.56)Co_(0.08)O_(2)was synthesized utilizing a Coprecipitation method and different amount of La(PO_(3))_(3)(La(PO_(3))_(3)=2 wt%,4 wt%and 6 wt%)was selected as the coating layer to resolve the above issues.During the calcination process,La(PO_(3))_(3)reacts with impurities such as Li OH and Li_(2)CO_(3)on the lithium-rich surface to reduce the residual lithium on the surface,thus improving the interfacial stability,slowing down the corrosion of the electrolyte,and finally enhancing its electrochemical performance.The cathode materials coated with 4%of La(PO_(3))_(3)showed the best electrochemical performance in terms of capacity retention and cycling performance compared to the pristine NCM.The high initial discharge capacity of 214.21 m Ah/g and capacity retention of 94.2%after 100 cycles at 0.1 C can be obtained.This work provides an effective strategy to protect the cathode from corrosion and will promote its further practical applications in high specific Li-ion batteries. | Miaomiao Zhou Jianjun Zhao Xiaodong Wang Ji Shen Wenhao Tang Yirui Deng Ruiping Liu | 2023 | Chinese Chemical Letters2023，34，6： | 1 |
