ZGA351 macroporous styrene serial anion exchange resin of strong basic type

Description

1. Description

“Hydrolite” ZGA 351 is a type of anion exchange resin containing a quaternary ammonium group [-N(CH3 ₎ 3OH _] in a washing-diethylenebenzene copolymer with a macroporous structure. It is primarily used to produce pure and ultrapure water, purify condensate water, and for wastewater treatment and precious metal recovery.
