The reaction between Ru(phen)32-(phen=phenanthroline)and Ce(Ⅳ) produces luminescence in aqueous solution.The effect of oxalate concentration on the intensity of chemiluminescence(CL)emission was firstly studied.CL intensity was linearly related to concentration of oxalate over the range of 3.0×10-8-2.9×10-6 mol/L.The detection limit was 1.5×10-8mol/L.The present paper reports this novel CL method for determination of oxalate,which is usually determined by electrogenerated chemiluminescence method.The method was evaluated by carrying out interference study with common ions and some co-existing compounds in human urine,by a recovery study and by the analysis of oxalate in human urine.The results obtained compared well with reference values.
