المستخلص:
A novel bidentate schiff bases were prepared from the condensation of 1,4 - bis - (aminomethyl)cyclohexan with 2,4 - dihydroxy acetophenon and 2,4 - dihydroxy benzaldehyde.Metal complexes of Co (III) , Cu (II) and Ni (II) with Schiff base A , B and C were prepared.A , B and C Schiff bases and their metal complexes were characterized via UV - Visible, FTIR and NMR. The metal complexes are expected to be octahedral in geometry based on physicochemical and spectroscopic analyses. New resins PoA and PoB were prepared by mixing Schiff base A and C with MDI respectively , thermogravimetric analysis of resins proved a good thermal stability.The study of loading capacity of resins towards transition metals showed that the PoA and PoB had high selectivity toward lead and zinc respectively.
