The physical properties of ion exchange resins are determined by their particle size, density, solubility and swelling properties.
Physical properties of ion exchange resins.

The full name of ion exchange resin consists of classification name, backbone (or gene) name, and basic name. Pore structure is divided into gel type and macroporous type. Any resin with physical pore structure is called macroporous resin, and "macroporous" is added before the full name. If the classification is acidic, "Yang" should be added before the name, and if the classification is alkaline, "Yin" should be added before the name. Such as: macroporous strong acid styrene cation exchange resin.

Chelating resins are functional polymer compounds with coordinating groups that can selectively chelate specific metal ions in the form of ionic bonds or coordination bonds from solutions containing metal ions.Mainly used for industrial wastewater treatment and recovery of divalent metals.

The use of ion exchange resins in mixed bed systems.
