Abstract
A cathodic bed of essentially inert, low cost silicon metal alloys in particulate form is used for the removal of ionic impurities from aqueous solutions by electrolytic deposition. The alloys used are substantially inert to the strong acid used to regenerate the alloy surface and remove the deposited metals.
