Chelating Resin

Compared with small molecule chelating agents, chelating resins have the advantages of simple synthesis, low cost, large adsorption capacity, easy elution, less interference, good mechanical properties and it is extremely stable for acids, bases and various solvents. Compared with ion exchange resins, chelating resins have stronger binding ability and higher selectivity to metal ions. When chelating resins chelate with specific metal ions, there will be many special physical and chemical properties, which are widely known as catalysts, photosensitive materials and antistatic agents.

Chelating resins are widely used in hydrometallurgy, analytical chemistry, marine chemistry, pharmaceuticals, environmental protection, geochemistry, radiochemistry and catalysis. In addition to being a metal ion chelating agent, it can also be used as a catalyst for oxidation, reduction, hydrolysis, olefin addition polymerization, oxidative coupling polymerization, and for the resolution of racemates of amino acids and peptides.

Chelating resin is a special ion exchange resin that can form a cross-linking functional polymer with a multi-coordination complex with metal ions. Among the functional groups, there are atoms such as O, N, S, P, and As which have unbonded lone pairs of electrons.

The heteroatoms on the chelating resin can form a coordination bond with a metal ion by a pair of lone pairs of electrons, forming a stable structure similar to a small molecule chelate. The polymer with chelation function needs to meet the requirements of two aspects, firstly, it needs to contain a coordination group, and secondly, the coordination group is arranged on the polymer backbone to ensure the space configuration requirements of the chelation process.

A chelating resin is a cross-linking functional polymer material capable of forming a multi-coordination complex with a metal ion.
