Hydrophilic reactive polymer gels, part V: Chelating resins with formazans as anchor groups based on sucrosemethacrylates

Abstract

The preparation and properties of hydrophilic chelating resins containing formazans as functional groups are described. Sucrosemethacrylat-gels with primary aromatic amino groups were diazotised and coupled with various substituted phenylhydrazones yielding gels with formazans as chelating anchor groups. The capacities of the gels were max. 1,6 mmol/g. The recycle of adsorption and elution was found to be satisfactory for Co2+ and Pb2+ whereas only 60% of the bonded Hg2− could be recovered reversibly.
