用三异辛胺（TIOA）-Span80-甲苯乳状液膜迁移Bi（Ⅲ）的研究表明，在合适的制乳和迁移条件下，Bi（Ⅲ）可以快速完全地迁入内相，并能与Fe3+、Co2+、Ni2+、Al3+、Cr3+、Mn2+、Cu2+、Pb2+、Cd2+完全分离。
Studies on the migration of Bi (Ⅲ) with TIOA-Span80-toluene emulsions show that Bi (Ⅲ) can quickly and completely migrate into the internal phase under appropriate conditions of emulsion and migration. Fe3 +, Co2 +, Ni2 +, Al3 +, Cr3 +, Mn2 +, Cu2 +, Pb2 +, Cd2 + completely separated.
