Abstract
The analysis of literature data on current-voltage characteristics (CVCs) and permeability of electromembrane systems in the processing of technological solutions of various industries is given. It is noted that electromembrane systems containing porous semi-permeable polymer membranes are insufficiently studied. The results of experimental studies on the CVCs of a membrane system equipped with an anode UAM-100, MGA-95 and near-cathode UAM-100, MGA-95 membranes during the separation of a model solution containing Mg2+, Fe2+, ions are presented. It is shown that in the study of membrane systems equipped with porous membranes, under the action of voltage and transmembrane pressure, as a result of the treatment of the model solution, two characteristic periods are noted on the CVCs (out-of-limit mode, intense electroosmotic transfer).
