摘要：

Chemical analysis of electrolytes in aqueous solutions is performed with a dialyzer consisting of two selective membranes: a cation and an anion-exchange membrane. The dialyzer actually functions like a galvanic cell when dialysis is carried out. The current that appears in the cell is measured. Since the dialysis process is caused by the concentration gradient, the current measured also depends on the concentration gradient. For proper conditions, it becomes possible to determine the concentration. The method may compete in some aspects with ion-selective potentiometry.
