Abstract

PURPOSE:To remove effectively and easily alkali chloride contained in the dust formed in combustion of conc. waste soln. from digestion step of pulp manufacture, by adsorption of the dust with amphoteric ion exchange resin of snake-cage type, and by elution of it. CONSTITUTION:Dust collected by an electric precipitator etc. during combustion of conc. waste soln. from pulp dibestion is dissolved in water to form a soln. of usually 5-40%, especially 20-30% solid content. The soln. is passed through a bed of amphoteric ion exchange resin of snake-cage type to adsorb alkali chloride contained in the dust. Then water is run through the resin bed having adsorbed alkali chloride so as to elute and recover the alkali chloride. The snake-cage type amphoteric ion exchange resin is constituted of basic radical-contg. cationic ion exchange resin of three dimensional structure and of acidic dical-contg. polymer of linear or three- dimensional structure which interwines the with former resin.
