Adsorption resin

The inquiry about this product

Ajinomoto Fine-Techno‘s adsorption resin, like activated carbon, consists of porous adsorbents that are mainly designed for physical adsorption. With a phenol-formaldehyde resin as its main component, functional groups—namely, the amino group and phenolic hydroxyl—coexist with each other. This induces ion exchanges by the functional group in acid and neutral areas, in addition to physical adsorption.
