Cardanol, a naturally occurring aliphatic chain substituted phenol derived from cashew nut shell liquid (CNSL) was used for the preparation of Schiff base ligand using 4-aminoantipyridine. The Schiff base complexes of Zr(IV) and Th(Iv) of di-α-formyl methoxybis(3-pentadecenylphenyl)methane (DFMPM) and 4- aminoantipyridine were synthesized in three stages. The ligand and complexes were characterized by UVvisible, IR Spectroscopy. The elemental analysis, melting point, metal ion intake, SEM, XRD, antibacterial and antifungal activity were also studied. The conductance measurements indicate that all the complexes of nonelectrolytes. The result indicated that the complexes of Zr(IV) and Th(IV) are hexacoordinated metal ion intake indicated the ligand can be used for the removal of these metals from water . The SEM and XRD studies revealed the nano crystalline nature of the complexes.
