Abstract: The researches on study of E-I characteristics of semipermeable membrane MGA-95P, OPM-K and OPMN-P in process medium of copperplating process are fulfilled. Experimental researches are carried out at installation with separation module. Module is two-chamber interface membrane apparatus of plate-and-frame type. In accordance with the received data the dependency diagrams of charge density from stress for solutions with copper ions and trisodium phosphate of different density were made. We see from the experimental data that all E-I correlations have dependence close to linear of charge density from stress. The implication of charge density do not have critical points, as in characteristic curve there are no inflection points. With the growth of concentration of dissolved solids in all the studied solutions charge density was also increasing.
