Abstract：The mechanism of extraction of Pt(Ⅱ)or Pd(Ⅱ)with N,N-disecondaryoctylg-lycine was investigated in the extraction system:H_2PtCl_4(or H_2PdCl_4) (?)/HCI(0.05—9 N)/(i-C_8H_(17))_2 NCH_2COOH CHCl_3(50 v.-%)-kerosene.The effects of con-centration of HCl,initial concentration of Pt(Ⅱ)or Pd(Ⅱ)and ionic strength(LiCl)in aqueous phase,extractant concentration in organic phase and phase ratio(A:O)on distribution ratio(D)were studied and the composition of the extrac-ted species of Pt(Ⅱ)and extractant was evaluated as H~+[PtCl_3(i-C_8H_(17))_2NCH_2-COOH]~- or[(i-C_8H_(17))_2NHCH_2COOH]~+[PtCl_3(i-C_8H_(17))_2NCH_2COOH]~-.And the extra-cted species of Pd(Ⅱ)and extractant was considered as(R_2NHCH_2COOH)~+[PdCl_3(R_2NCH_2COOH)]~-. 收稿日期: 1985-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 章健民 章爱铀 何振宇 马光甲 袁承业 周莉影 涂通源 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I5/85 1 Edwards,R.I.,Proc.Int.Solvent Extraction,Conf.,ISEE 77,CIM Special Vol.21,Canadian Inst.of Min.& Metall.,1979,p.24． 2 Edwards,R.I.,Ger.Offen.,2 726 557;CA.,88(1978) ,108 659C. 3 Sevdic,D.;Meider-Gorican,H.,J.Less-Common Met.,37(1974) ,103． 4 Ginzburg,S.I.;Ezerskaya,N.A.,Analytical Chemistry of platinum Metals,Wiley,New York,1975,p.339． 5 株洲冶炼厂等编,有色冶金中元素的分离与测定,冶金工业出版社,1979,p.446． 6 徐光宪,化学学报,27(1961) ,93． ;黎乐民;白明璋;徐光宪,科学通报,(1963) ,№1,55;黎乐民;徐光宪,科学通报,(1966) ,№1,20． 7 Ginzburg,S.I.;Ezerskaya,N.A.,Analytical Chemistry of platinum Metals,Wiley,New York,1975,p.70． 8 Davies,J.A.;Hartley,F.R.,Chem.Rev.,81(1981) ,79． No related articles found!
