Synthesis and characterisation of polymer supported schiff base metal chelates

摘要

Divinyl benzene (DVB)-crosslinked polystyrene has been functionalised to introduce thiosemicarbazone ligand function. This Schiff base thiosemicarbazone ligand is used to prepare chelates of Fe(III),Co(II),Ni(II),Cu(II) and Zn(II).The factors influencing metal complexation like temperature,pH,influence of solvent etc are examined. The polymeric metal complexes are well characterised by spectral techniques and assigned a proper geometry on the bais of analyticla,magnetic measurement and spectral data.
