1. Description:

“Hydrolite” ZGA 307-w is an anion exchange resin containing a quaternary ammonium group [-N(CH3 ₎ 3OH _] in a styrene-diethylenebenzene copolymer. It is specifically used for the separation and purification of tungsten and molybdenum in hydrometallurgy and is characterized by high ion exchange capacity and good resolution.
