一、基本信息

【产品简介】：Cation exchange resin is a special type of resin that contains acidic groups in its molecular structure, which allows it to swell in water or polar solvents. When the cation exchange resin comes into contact with water, its acidic groups release hydrogen ions, making the aqueous solution acidic. More importantly, this resin can exchange with cations in other solutions through hydrogen ions, potassium, sodium ions, etc., effectively removing harmful cations from the solution.

According to the ionization constant of acidic active groups, cation exchange resins can be divided into three categories: strong acidity, moderate acidity, and weak acidity. Strong acidic cation exchange resin contains sulfonic acid group SO3H, which has a high ionization constant and can exchange with various cations. Medium acidic cation exchange resin contains phospho H2PO4 or phospho H2PO3, which have a moderate ionization constant and can exchange with most cations. Weakly acidic cation exchange resins contain carboxyl COOH or phenolic hydroxyl groups, which have lower ionization constants and can only exchange with some cations.
