　　氯化钠能使正丙醇水溶液分为醇／水两相，在此分相过程中，罗丹明 B（RhB）和 SbCl－6生成的三元缔合物[SbCl－6][RhB＋]可被完全萃取．研究了罗丹明 B 和盐酸的浓度对萃取的影响．结果表明，当溶液中罗丹明 B 和盐酸的浓度分别为0．2 g／L 和0．4～1．5 mol／L 时，Sb 5＋的萃取率达到99．1％以上，可以使 Sb Ti 4＋、Rh 3＋、Sn 4＋和 Ag＋分离．5＋与

The 1-propanol aqueous solution could be well divided into 1-propanol /water two phases in the pres-ence of sodium chloride.The ternary complex [SbCl-6 ][RhB+] formed with Rhodamine B and SbCl-6 could be com-pletely extracted during this process .The influences of concentrations of Rhodamine B and hydrochloric acid on extrac -tion were studied.The results showed that Sb 5 + could be quantiatively separated from Ti 4 +,Rh 3 +,Sn 4 +and Ag+ by ex-traction,and values of extraction percentage of Sb 5 +reached over 99.1%.when the concentrations of Rhodamine B and hydrochloric acid in solution are 0.2 g/L and 0.4 ~1.5 mol/L,respectively.
