Heavy metal removal process
摘要:
An ion-exchange media comprising a modified polysaccharide material and a modified silica material, said modified materials comprising a polysaccharide and silica materials covalently bonded to a synthetic polymer, said synthetic polymer comprising a copolymer made from a polymerization of:(a) a polymerizable compound having a chemical group capable of covalently coupling, directly or indirectly, to said materials; and(b) a polymerizable compound containing (i) an ionizable chemical group or (ii) a chemical group capable of transformation to an ionizable chemical group.The media is used to selectively remove heavy metal contaminants from aqueous solutions containing said contaminants.
