ZGA 455 styrene series macroporous weakly basic cinnamene anion exchange resin
1. Description:
The “Hydrolite” ZGA 455 is a sort of anion exchange resin that has tertiary amine group [-N(CH3)2] in the cinnamene styrene and diethenoid benzene copolymer with macroporous structure. It is used mainly to absorb and recover aurum in the solution and waste water that contains aurum, absorb and recover hexavalent chrome in the solution and waste water that contains chrome, absorb and recover hexavalent hydrargyrum in the solution and waste water which contains hydrargyrum.
