Abstract
PURPOSE:To dissolve and remove heavy metal hydroxides attached to a cation exchange membrane in a NaCl electrolytic cell by carrying out electrolysis at the same current density with diluting a caustic soda soln. in the cathode chamber as well as supplying an acidic aq. NaCl soln. of pH 1 or below into the anode chamber.
