D 836 Arsenic Removing Resin is a special resin, it is a macromolecule copolymer with special functional group in a surface heat treated polymer containing an active iron group on a styrene-divinylbenzene matrix Active iron can form a very stable complex compound with arsenic acid and is inert to other anions. Due to its special functional group, it has extremely high selectivity to arsenic acid, and the adsorption capacity of arsenic acid is basically not affected by other ions in the solution, so it is very suitable for removing arsenic acid in various aqueous solutions.
Advantage:
) Extremely high selectivity to arsenic acid
2) Good selectivity
3) Excellent mechanical strength
4) Large exchange capacity.
