Two Ce(Ⅲ)_amino acid_imidazole teranry complexe were synthesized,These complexes have the composition of Ce(Trp) 3IM(NO 3) 3·3H 2O and Ce(Phe) 3IM(NO 3) 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.
