Abstract

PURPOSE: To enable to operate with a high current density, to prevent the deterioration of the membrane due to the sludge of brightener, etc. and to concentrate and separate the heavy metal salts economically advantageously from the aqueous solutiin of heavy metal salts, by carrying out the electrodialysis using the diaphragm obtained by comining the neutral diaphragm and the cation exchange membrane.
