Transport of 125I and 36Cl across an anion-exchange paper membrane.
The membrane characteristics controlling 125I and 36Cl transport across anion-exchange paper membranes are examined using three different paper membranes treated with different anion exchange groups: a trimethylhydroxypropylamino group, a diethylaminoethyl group, and a 50% quaternary diethylaminoethyl group. The membrane permeability for 125I is higher than that for 36Cl in all cases. Treatment with trimethylhydroxypropylamino group improves the 125I diffusion process, and the use of 50% quaternary diethylaminoethyl group improves the 125I solution/membrane distribution process.
