Abstract

A novel method for the separation/enrichment of trace Bi3+ using microcrystalline thymolphthalein loaded with diacetydioxime was established. The effects of different parameters on the enrichment yield of Bi3+ have been investigated. The possible enrichment mechanism of Bi3+ was discussed. The results showed that under the optimum conditions, in diacetydioxime (DMG)-thymolphthalein (TP) system, the chelate settlement of [Bi(DMG)2] which formed by Bi3+ and DMG was quantitatively adsorbed on the surface of microcrystalline thymolphthalein, and the liquid-solid phases were formed with clear interface, while Cd2+,Zn2+ and Mn2+ could not be adsorbed. The quantitative separation of Bi3+ from those metal ions was achieved. A new method for the separation enrichment of trace Bi3+ was established. The proposed method has been successfully applied to the quantitative separation of trace Bi3+ in the samles of synthetic water, and the enrichment yield was 94.4%~100.9%.
