SYNTHESIS CHARACTERIAL AND ANTIBACTERIAL ACTIVITY OF THE COMPLEX YTECBIUM WITH MIXED LIGAND L- ASPARTIC AND OPHENANTHROLINE

Abstract

    The complex of ytecbium with mixture ligand L-aspartice and o-phenanthroline wasseparated from the solid. The element and structure of the complex have beenspecified by elemental analysis method, thermal analysis method, infrared absorptionspectrum (IR). The researching of biological activity showed that the complex is ableto inhibit the growth of pathogenic bacteria species: Escheria coli, Bacillus subtilis,Staphylococcus aureus, Seratia macescen in different concentrations from 20 to 60μg/ml. The inhibition increases the following concentration.

Keywords: complex, ytecbium, L-aspartic, o-phenanthroline, biological activity.
