Hydrophile Polymergele mit reaktiven Gruppen, 5. Mitt.: Chelatharze mit phosphorhaltigen Ankergruppen auf Basis von Saccharosemethacrylaten

摘要

Phosphorus containing chelating resins were synthesized by reaction of sucrosemethacrylate gels with various dialkylester halides of phosphoric acid and thiophosphoric acid. The sorption capacities of the hydrophilic gels were found to be max. 3.7 mmol/g and equilibrium was achieved within 5 minutes. The recycle of adsorption and elution was found to be satisfactory for Zn2+and Cu2+whereas only 50 of the bonded Hg2+could be recovered reversibly.
