ZGC 258 macroporous acrylic acid series weakly acidic cation exchange resin
1. Description
The “Hydrolite” ZGC 258 is a sort of cation exchange resin that has carboxylic acid group (-COOH) in the acrylic acid copolymer with macroporous structure. It is used mainly to treat industrial water, especially remove bicarbonate and carbonate and other basic salt species, as well as recover and treat waste water which contains zinc and nickel, separate and purify biochemical medicine and so on.
