ACD 161 Chelating Resin The Ultimate Solution for Arsenic Removal and EINECS No. 202-851-5
ACD - 161 employs a styrene - divinylbenzene cross - linked copolymer as its base material. Through the application of suspension polymerization technology, a robust framework with high mechanical strength is established.
Leveraging a patented nano - dispersion technique, the resin's surface is evenly coated with active sites derived from rare metal oxides, including iron (Fe) and zirconium (Zr). This results in the formation of a stable metal - organic coordination complex on the resin.
In addition, through specific surface modification procedures, functional groups like amino and phosphonate groups are incorporated onto the resin surface. These modifications substantially boost the resin's capacity for selective adsorption of arsenate ions.
