the properties of charge-mosaic membrane prepared from irradiated poly(styrene-butadiene-4-vinylpyridine) triblock copolymer were investigated. The results showed that the fluxes of water and electrolyte through the membrane are 2.40×10-5 mol/cm-3 min
and 2.10×10-3 mol/cm-2 sec respectively when the concentrations of KCl are 0.1 mol/1 and 10-3 mol/1 on the two sides of membrane. Experimental results of separation showed that charge-mosaic membrane has better dialysis properties for permeation to salt but not to high mole-cular weight or low molecular weight non-electrolytes.For mixed solution of KCl and protein
KCl and sucrose
the fluxes of KCl are 1.07×10-8 mol/cm2sec and 1.10×10-8 mol/cm2sec respectively.
