Hydrophile Polymergele mit reaktiven Gruppen, 4. Mitt.: Chelatharze mit schwefelhaltigen Ankergruppen auf Basis von Saccharosemethacrylaten

摘要

Chelating resins with thioglycolate anchor groups have been synthesized by reaction of sucrosemethacrylate gels with thioglycolic acid. The capacities of the gels were found to be extremely high for Ag+(5,3 mmol/g) and Hg2+(4,9 mmol/g). About 1 mmol Hg2+/g could be recovered from the gel reversibly by treatment with hydrochloric acid. The removal of Hg2+from aqueous 3Malkalichloride solutions was possible with capacities of 1 mmol/g.
