Abstract
PURPOSE: To decolor a sulfonic acid type cation exchange resin consisting basically of a divinyl benzene-styrene copolymer without lowering the capacity as a resin by bringing said resin into contact with an aq. soln. of an oxidizer such as sodium hypochlorite or the like.
CONSTITUTION: The above-mentioned sulfonic acid type cation exchange resin of gel type, porous type, or the like of usually about 2W20% degrees of cross-linking is subjected to decoloring treatment in the following way: this resin is brought into contact with an aq. soln. of sodium hypochlorite, calcium hypochlorite or H2O2, whereby the resin is decolored. The concns. of the aq. soln. of this case are about 0.1W14% sodium hypochloride as available chlorine, about 0.1W10% calcium hypochlorite as available chlorine and about 1W30% H2O2. The catalytic treatment temps. are about 0W100°C, more particularly about 10W50°C. The resin decolored by this method is the cation exchange resin of extremely high merchandise value.
