Abstract

PURPOSE: To wash and regenerate cation exchange resins efficiently by bringing mixed solns. consisting of formaldehyde sulfoxylate, amino polycarboxylic acid salt and neutral salt for resin regeneration into contact with said resins.
CONSTITUTION: In the case of regenerating and washing cation exchange resins, solns. of formaldehyde sulfoxylate, salt of amino polycarboxylic acid and neutral salt for regeneration are supplied into a tower. The mixed solns. contg. the above-described three are brought into contact with the cation exchange resins in the state of counter current or parallel current by backwashing with said solns., whereby the resins are regenerated and the iron hydroxide and other foreign materials stuck on the resins are stripped. There are trisodium ethylenediaminetetraacetate, etc. for the salt of amino polycarboxylic acid and there are an aq. sodium chloride soln., an aq. potassium chloride soln., etc. for the neutral salt soln.
