and geometric properties of free and embedded dithizone molecules[J]. International Journal of Quantum Chemistry, 2002, 86(1): 90-99. Extraction and separation of trace zinc ion in sodium phosphate solution... of trace zinc(II) in sodium phosphate solution was studied by dithizone extraction. The solubility of dithizone in toluene, benzene, chloroform and carbon tetrachloride was investigated experimentally......
Principle of extraction Alkyl phosphate extractant D2EHPA often exists in dimer form in kerosene solution. Zinc can be extracted using D2EHPA (expressed as HR) by the following reactions:  ... of zinc, cadmium and chromium from phosphoric acid solutions by tri-n butyl phosphate in kerosene diluent [J].

Post-sealing the phosphated HDG steel with silicate solutions, the pores among the zinc phosphate crystals are sealed with the films containing Si, P, O and Zn... be formed[8]. Neighboring these compounds, the chemical activity is higher, facilitating the precipitation of the zinc phosphate crystals. Therefore, the crystal nuclei of zinc phosphate are increased......
磷酸三丁酯萃取-火焰原子吸收光谱法测定高纯黄磷中痕量铁和锌李佳1,朱晓帆2,许凤兰2(1.四川省成都市四川大学建筑与环境学院2.四川大学 分析测试中心,四川成都 610065)摘 要:用火焰原子吸收光谱(FAAS)法直接测定高纯黄磷消解液中痕量Fe和Zn,结果发现抑制作用很强.磷酸三丁酯(TBP)作为萃取剂可将高纯黄磷消解液中的磷酸萃取分离,从而降低磷酸与Fe,Zn的络合作用同时降低磷酸的黏度,减少了用FAAS测定高纯黄磷中痕量Fe与Zn的抑制作用.试验优化后的萃取条件为:样品和TBP的体积比为1∶1,振荡1 ......
