Case Study

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.

The immobilized enzyme is a biological reagent with high efficiency, high selectivity and mild reaction conditions.

In the immobilized enzyme technology, factors such as the active group, the microenvironment, and the shape of the carrier on the carrier material may affect the affinity of the carrier and the enzyme, the activity, stability, reusability and recyclability of the immobilized enzyme.

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.

The adsorption resin is mainly formed by suspension polymerization, and the pores are formed inside the resin through the addition of the porogen, followed by rinsing, sieving and the like.

The adsorption is mainly based on the principle of van der Waals force or hydrogen bonding to produce adsorption.

Adsorption separation is an exothermic process and macroporous adsorption resins can be regenerated by heating. It can also be treated with a regenerant.
