摘　　要：在氯化钠存在下,正丙醇水溶液能够分为醇/水两相,在分相过程中,SbCl6-与罗丹明B(RhB)生成的[SbCl6-][RhB+]三元缔合物能被正丙醇相完全萃取。使Sb5+与Ru3+、Ag+、Cr3+、Cu2+、Mg2+、Fe3+、Ni 2+和Co2+完全分离。该法在微量锑的分离和富集分析中有一定的实用价值。1-Propanol aqueous solution could be well divided into 1-propanol/water two phases in the presence of sodium chloride.The ternary complex [SbCl-6] formed with SbCl-6 and Rhodamine B could be completely extracted during this process.Sb5＋ could be quantiatively separated from Ru^3＋,Ag^＋,Cr^3＋,Cu^2＋,Mg^2＋,Fe^3＋,Ni^2＋ and Co^2＋ by extraction.This method is practicable in separation and enrichment analysis of trace antimony.
