SYNTHESIS, CHARACTERIZATION AND BIOCHEMICAL STUDIES OF CERIUM(III), PRASEODYMIUM(III) AND NEODYMIUM(III) CHELATES WITH 1-HYDROXY-2-PROPANONE

Abstract

The combination of selective rare earth metal ions with biologically active molecule to form metal-ligand complex is an important area of current research. Lanthanide ions are having typical chemical and physical properties. For example, Lanthanide contraction, magnetic properties etc. On complexation of bio-active molecule capable of forming chelate ring with three lanthanide metals ion Ce (III), Pr (III), and Nd (III), there is a drastic change in chemical and biological properties have been observed. Less explored and biologically active 1-Hydroxy-2-propanone ligand is used to form complexes. Thus obtained complexes are subjected to characterization by laboratory methods and instrumental methods including spectroscopic methods. Antimicrobial studies were carried out by standard methods and then catalytic activities of Ce-HA, Pr-HA and Nd-HA complexes are studied by using standard chemical reaction. The difference in properties of metal ions, ligand and chelates is becoming a very important study area.
