Abstract: Tb(Ca)-glycine,Tb(Ca)-alanine, Tb(Ca)-glycine-alanine systems were studied by potentiometry(37℃, I=0. 15 mol/L NaCl).The stability constants of complexes and distribution of species in ternary system were obtained.The results show Ca<Tb for the stability of binary complexes,Ca>Tb for the ternary complexes.The species convert each other with changing pHvalues.

Key words: Terbium, Calcium, Amino acid complexes
