Uranium Extraction Anion Exchange Resin

Lanlang ® TA463D is an anion exchange resin with weak base groups [-N+(R2)·H2O] on a macroporous acrylic framework. Mainly used for the extraction, separation, and concentration of uranium in alkaline leaching uranium mines.

The alkaline leaching method contains a large amount of free humic acid and hydrosulfites in the leaching solution. When using styrene based strong alkaline anion resins, these impurity ions cannot be leached together during the usual leaching process, and continuously accumulate on the anion resin, thereby affecting the adsorption of uranium. This phenomenon is called organic matter pollution of ion exchange resins.

The special acrylic framework and macroporous structure of Lanlang ® TA463D resin have high uranium saturation adsorption capacity, excellent resistance to organic pollution, good hydrophobicity, anti osmotic pressure strength, and stable physicochemical properties. It can effectively avoid the pollution of anion resin and maintain its long-term adsorption performance for uranium.
