镉离子在三正辛胺为载体的支撑液膜中的传输

Transportation and concentration of Cd 2+ with supported liquid membrane of TOA

用三正辛胺为载体，聚丙烯微孔膜为支撑体的支撑液膜体系处理含镉料液。

The polyacryl liquid membrane was made into surpported material for concentration of Cd 2+ .The best working conditions are as follows:0 12 mol/L TOA concentration;0 05 mol/L NaOH for reverse contracted phase;pH0.5 for raw material phase;1 0 mol/L for Cl - in addtion,it is good for permeation of Cd 2+ ion to increase the concentration of I -.
