稀土与甘氨酰-L-亮氨酸的配位作用
English
Coordination of Rare Earth with Glycyl-L-Leucine
Abstract:
Protonation constants of the title ligand as well as stability constants of its com-plexes with rare earth elements were determined by pH potentiometric titration in the physio-logical conditions and at 25℃,I=0.10mol/L respectively. The results indicate that the rare earth can form 1:1 coordination compounds with glycyl-L-leucine at the studied range of pH. There is an obvious "tetrad effect" in the system. Yttrium position and the effect of peptide bond on the complex stability were discussed.
