Abstract

PURPOSE: To separate heavy metal ions promptly on the surface of a cathode, by electrolyzing caustic alkali soln. contg. heavy metals such as Fe or Ni etc. (particularly one from diaphragm electrolysis method) in an electrolyzer having cathode consisting of netted or porous plate form metal laminated body in which liq. may be passable.
