Dragonlite-SN7 is a sort of 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.
