Abstract
O-Vanillin derived schiff base ligands were synthesized with 1,3-diaminapropane and oxamidei.e L1 and L2. These schiff base ligands were then used to synthesize mononuclear schiff base metal complexes by treating them with Fe3+, Co2+,Mn2+and Zn2+ metal salts, giving L1Fe, L1Co, L1Zn and L2Co, L2Mn metal complexes. L1 and L2ligandsand L1Fe, L1Co, L1Zn and L2Co, L2Mn metal complexes were characterized by FT-IR, UV-vis and PXRD. The synthesized metal complexes were used against rhodamine blue (RB) dye for their comparative study of degradation properties. Among the synthesized complexes L1Co showed maximum degradation of RB after 70 min of interval of about 56.835% whereas, the degradation property shown by L1Zn, L1Fe, L2Co and L2Mn is 42.446%, 32.733%, 20.863% and 13.309% respectively. The order of degradation of RB by all the metal complexes is as follows; L1Co> L1Zn> L1Fe> L2Co> L2Mn.
