1.Brief Introduction:
This product is the anion exchange resin that has quaternary ammonium group [-N(CH3)3OH] in the styrene-diethylene benzene copolymer with 7% cross linking degree. It is used mainly to produce pure water and treat wastewater and extract tungsten and molybdenum in biochemical product and hydro-metallurgy.
This resin series include three types,among which LH-207 is a general one:LH-207FC is for strata bed,double bed,fluidized bed system;LH-207MB for mixed bed system.
