Synthesis, characterization and biological activity of chelated minerals

Cobalt, Copper and Zinc complexes of amino acids [lysine and glycine] were prepared and characterized by IR, electronic absorption spectra, elemental analysis, magnetic susceptibilities, the differential thermal analysis [DTA] and thermal gravimetric analysis [TGA] of the complexes pointed to their stability. The thermodynamic parameters of the dissociation steps are evaluated. The metal chelates and ligands have been screened for their invitro antibacterial against. Bacillus cereus, Salmonella yeast, E-coli and Staphylococcus. The metal complex [copper glycine] was shown to posses more antibacterial activity than the unchelated ligands. The adsorption ability of complexes to aflatoxin has been studied
