Abstract

Two Ce(Ⅲ)-amino acid-imidazole teranry complexe were synthesized,These complexes have the composition of Ce(Trp)₃IM(NO₃)₃·3H₂O and Ce(Phe)₃IM(NO₃)₃ respectively. The IR spectra indicate that the carboxy group of amino-acid and the N atoms of imidazole are coordinated with Ce(Ⅲ) ion. Cyclic voltammetry was used to study the electrochemical behaviour of Ce(Ⅲ) ion, the mixture of Ce(Ⅲ) with ligands, and Ce(Ⅲ) binary or ternary complexes. Within the scan range of -0.1 to 1.10 V (vs.SCE), both of ternary complexes depicted completely irreversible electron transfer process.
