ZGA412 weakly basic acrylic acid series anion exchange resin
1. Description
The “Hydrolite” ZGA412 is a sort of anion exchange resin which has tertiary amine group [-N(CH3)2] in the cross linking crylic acid framework with macroporous structure. It has excellent absorption ability to organic substance in natural water, and can release it conveniently in the regenerating process, so the anti-pollution ability to organic substance is very primely. It is used mainly to produce pure water while the water resource contains high contention of organic substance and salt, with the characteristics such as high working exchange capacity and low regenerating specific consumption.
