Adsorbent resin, also known as polymer adsorbent, is a kind of high molecular polymer which has the function of adsorption and concentrates and separates organic matter.
According to the surface properties of the resin, the adsorption resin is generally classified:
non-polar adsorption resins which are obtained from a monomer polymer having a small dipole moment. A typical example of an adsorption resin having any functional group is an adsorption resin of a styrene-divinylbenzene system;
a medium polarity adsorption resin means an ester-containing adsorption resin such as acrylate or methacrylate and dimethacrylate. A type of copolymer which is cross-linked;
a polar adsorption resin refers to an adsorption resin containing a nitrogen, oxygen, sulfur polar functional group such as an amide group, a cyano group or a phenolic hydroxyl group.
