Abstract

PURPOSE: To stably carry out dialysis with a high electric current efficiency without producing scale on the face of ion exchange resin, by turning on an electric current maintaining pH of concentrated liquid in a fixed extent, on occasion of supplying water solution of zinc mineral acid salt in dilution room of electrodialysis vessel and concentrating and recovering the above salt.
CONSTITUTION: On occasion of supplying water solution of zinc mineral acid salt in dilution room of electrodialysis vessel and concentrating and recovering the above salt in concentration room, pH of concentrated liquid is maintained at 1W2.5, preferably 1W1.5, by adding acid and moreover, a part of the concentrated liquid is drawn out and then, dialysis is carried out maintaining the concentration of the above salt in the liquid of concentration room at less than 40g/l. by the above method, acidity added during dialysis, is able to decrease and neutralization treatment necessary for abandonment, is easily carried out because acid quantity in diluted solution is small after recovering Zn.
