Synthesis and Characteristics of A Novel Heavy Metal Ions Chelator刘转年College of Geology and Environment,Xi’an University of Science and Technology摘 要:Polyacrylamide-urea-sulfanilamide(PUS) was prepared as a novel heavy metal ions chelator and successfully used to simultaneously remove heavy metals from wastewater effluents.The effects of reaction......
Sodium Alginate/Carboxyl-Functionalized Graphene Composite Hydrogel Via Neodymium Ions CoordinationQianqian Huang,Shunli Liu,Kewen Li,Imtiaz Hussain,Fang Yao,Guodong FuSchool of Chemistry... was developed. Based on the coordination ability of lanthanide ions to the carboxyl groups, a series of hydrogel derived from different ratios of SA and G-COOH was fabricated by neodymium(Nd3+) ions......
Ab initio calculation of electronic structures and 4f-5d transitions of some rare earth ions doped in crystal YPO4 YIN Min1,WANG Dajun1,XIA Shangda3 (1.Hefei National Laboratory for Physical... in a microcrystal containing about 1500 ions, respectively. The ground-state calculation provided the locations of the 4f and 5d crystal-field one-electron levels of RE3+ relative to the valence and conduction......
and structure characterization of N,N’-diethoxycarbonyl-N’’,N’ ’’-(1,6- hexylidene) dithiourea and its coordination with metal ions YUAN Lu, ZHONG Hong, LIU Guang-yi, GUO Yan, CHEN Mao, LI Li-qing (Key... with three ions separately, and has a best selectivity to Fe3+. Compared with the IR spectral data of compound, the structure of the precipitate is of annular chelate. Key words: diethoxycarbonyl dithiourea......
Trans. Nonferrous Met. Soc. China 27(2017) 1411-1416 Impurity distribution in distillate of terbium metal during vacuum distillation purification Xiao-wei ZHANG, Rui-ying MIAO, Dao-gao WU, Qiong ZHU... experiment and theoretical analysis. It is found that Ti impurity in distilled terbium is 220 mg/kg in the initial stage of the distillation purification, increases slowly in the middle stage, and increases......

ARTICLE J. Cent. South Univ. (2019) 26: 323-330 DOI: https://doi.org/10.1007/s11771-019-4004-z Salt ions accumulation and distribution characteristics of pioneer plant species at a bauxite residue... in an abandoned BRDA in Central China. The pioneer plant species at the disposal area were identified, whilst distribution characteristics of salt ions such as Na+, K+, and Ca2+ in plant tissues......
the cooperative sensitized luminescence from Cu2+ or Pb2+ by three clustered Yb3+ ions, in which three NIR photons can be converted into a high energy photon. Could a reverse process happen that a high energy photon is cut into three NIR photons? This work demonstrated an example of three-photon quantum cutting(QC) phosphor,CaF2:Ce3+,Yb3+, in which three clustered Yb3+ ions(Yb3+-trimer) cooperatively......
