本文研究了N，N-二仲辛基甘氨酸在H_2PtCl_4（或H_2PdCl_4）（？）HCl（0.05-9 N）/（i-C_8H_（17））_2NCH_2COOH CHCl_3（50体积%）研究了HCl浓度、Pt（Ⅱ）或Pd（Ⅱ）初始浓度和离子强度对Pt（Ⅱ）和Pd（Ⅱ）的络合作用（LiCl）、有机相中的萃取剂浓度和相比（A：O）对分配比（D）的影响，确定了Pt（Ⅱ）和萃取剂的萃合物组成为H~+[PtCl_3（i-C_8H_（17））_2NCH_2-COOH]~-或[（i-C_8H_（17））_2NHCH_2COOH]~+[PtCl_3（i-C_8H_（17））_2NCH_2COOH]~-，并认为Pd（Ⅱ）与萃取剂的萃合物为（R_2NHCH_2COOH）~+[PdCl_3（R_2NCH_2COOH）]~-。
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)]~-.
