ZGA 307 styrene series strongly basic anion exchange resin

 

1. Description

The "Hydrolite" ZGA 307 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.

2. Executing standard: GB/T13660-1992   DL/T519-2004   SH2605.06-2003
