Reactions of 16 organic acids with Ru(phen)~3^2^+ (phen=1,10-phenanthroline) and Ce(Ⅳ) were examined for chemiluminescence (CL) light emission. Organic acids with C=O or OH group were found capable of increasing the CL light emission. CL intensity were linearly related to the concentration of them. The method has been satisfactorily applied to determine free oxalic acid in diethyl oxalate and oxalate in human urine. A coupled Cl reaction mechanism is presented.
