Yuhui A-SQ-II is a premium grade gel-type strong base anion (SBA) exchange resin based on styrene-divinylbenzene (DVB) copolymers with type-II quaternary amine (Dimethylethanolamine) function group and standard Gaussian particle size distribution. Due to the special function group A-SQ-II has excellent regeneration efficiency without strong amine odor comparing to conventional type-I SBA resin. A-SQ-II is developed to be used for industrial water demineralization when it works in hydroxide form and to remove anions when it works in chloride form, including sulfate, nitrate, arsenate, chromate and silicate.
