| titleOfInvention | A chelating resin containing sulphonic acid groups used in the adsorption of heavy metal ions |
| abstract | The present invention relates to a sulfonate group-containing chelate resin for adsorption of specific heavy metal ions, and more particularly, a spacer having an N-methylsulfonamide bond structure is introduced into a phenyl side chain of a spherical polystyrene copolymer. In addition, the sulfonic acid group is subsequently introduced into the chelate functional group to form a more hydrophilic structure, and around the sulfonic acid functional group, the non-covalent electron pairs of oxygen or nitrogen atoms are further enriched, so that the specific adsorption properties for specific heavy metal ions are excellent. It relates to a sulfonic acid group-containing chelate resin for heavy metal ion adsorption. |
