Comcess provide a wide variety of chelating resins that exhibit superior selectivity for specific target ions over ion exchange resins. The adsorption mechanism of chelate resin to metal ions is that the functional atoms on the resin coordinate with metal ions to form a stable structure similar to small molecule chelates, while the adsorption mechanism of ion exchange resin is electrostatic interaction. Therefore, compared with ion exchange resins, chelating resins have stronger binding force to metal ions and higher selectivity. It can be widely used in the recovery and separation of various metal ions, the separation of amino acids, hydrometallurgy, pollution prevention and other fields.
Application: adsorption and extraction of precious metal ions such as gold, platinum and palladium.
