Anion exchange resin is a type of insoluble high molecular weight spherical polymer with alkaline active groups, fixed with positively charged functional groups on the skeleton, which can dissociate into exchangeable anions and undergo reversible ion exchange with anions such as sulfate, chloride, nitrate, silicate, bicarbonate, etc. in water.
Main applications:
Water treatment: A desalination system composed of cationic resin is used to produce pure water and ultrapure water;
Solution decolorization and organic acid purification in the chemical, pharmaceutical, and food industries;
Treatment of heavy metal wastewater and electroplating wastewater to remove anionic pollutants.
