D805 Weak Acid Cation Resin Based for Copper Adsorption Resin
D805is a macroporous weak acid cation resin based on the iminodiacetate acid function group, which mainly used for separation recovery and adsorbent of bivalence metals, also used for brine refining in the process of ion membrane soda producing industry. It has good selectivity for calcium and magnesium with large exchange capacity and physical strength.
