Transport of Zn(OH)4(-2) Ions Across a Polyolefin Microporous Membrane
Abstract
Transport of ZN(OH)4(2-) ions through modified microporous polypropylene membranes (Celgard 3401, 35014 was studied using polarography and conductometry. Soluble Nafion as an ion exchange modifying agent was applied to the membrane by several techniques. The influence of Nafion and a surfactant on transport of zinc ions through the membrane was studied. A relationship between membrane impedance and the rate of Zn(OH)4(2-) transport was found. The found correlation between conductivity, ion permeability and Nafion coverage suggests a suitable technique of membrane preparation to obtain desired zinc ion barrier properties.
