Synthesis,Characterization and Bacteriostasis of Rare EarthComplexes with Salicylaldehyde Amino Schiff Base

The complexes of rare earth with tyrosine Schiff base were synthesized.The composition of the complexes was determined by EDTA capacity analysis and elemental analysis,and they were characterized by molar conductivity,IR,UV and TG-DTG analysis.Bacteriostasis experiments show that both the ligand and the complexes have varying bacteriostasis effect for escherichia coli,but the complexes have higher activity than the ligand.
