Ion complexation by silica-immobilized polyethyleneimines |
摘要 |
Metal ions are removed from solution by complexing with an immobilized polyethyleneimine, formed by first bonding a silane-propyl bridge to a substrate particle of silica or silicate, larger than 200 mesh. Then, polyethyleneimine is covalently bonded by a nitrogen to the bridge. Due to the spacing established by the bridge between the polyethyleneimine and substrate, the polyethyleneimine maintains high ion complexation capacity.
