styrene series strongly basic anion exchange resin
1. Description
It a sort of anion exchange resin that has quaternary ammonium group [-N(CH3)3OH] in the styrene-diethylene benzene copolymer with 4% cross linking degree. It is used mainly to produce pure water and ultra pure water and decolorize sugar solution and extract biochemical substance and radioelement.
