ZGA 307 styrene series highly basic anion exchange resin

Description

1. Description

“Hydrolite” ZGA 307 is a type of anion exchange resin containing a quaternary ammonium group [-N(CH3 ₎ 3OH _] in a styrene-diethylenebenzene copolymer with a crosslinking degree of 7%. It is mainly used for clean water production, wastewater treatment, and the removal of tungsten and molybdenum in biochemical products and hydrometallurgy.
