Chealting Resins for the Recovery and Separation of Various Metal Ions

Chelating resins are a kind of crosslinking functional polymer materials that can form multi-coordination complex with metal ions. The mechanism of chelating resin absorbing metal ions is the coordination reaction between the functional atoms on the resin and metal ions, forming a stable structure similar to small molecule chelates.

Compared with ion exchange resins, chelating resins have a stronger binding force and a higher selectivity with metal ions. It is widely used in various metal ion recovery and separation, amino acid separation, hydrometallurgy, public hazard control, etc.
