ZGA451 macroporous styrene weakly basic anion resin

Description

1. Description

“Hydrolite” ZGA 451 is a type of anion exchange resin containing a tertiary amino group [-N(CH3 ₎ 2 _] in a styrene-diethylenebenzene copolymer with a macroporous structure. It is used primarily to produce pure and ultrapure water, and is particularly suitable for treating water with high salt and organic content, as well as for purifying chromium-containing wastewater and decolorizing sugar solutions, etc.
