| Abstract: | The chemiluminescence reaction of iso-propal alcohol with CLO-H2O2 is enhanced by acetalde-hyde. This provides a novel chemiluminescence method for the determination of acetaldehyde. The linear range of the method is 5×10-10g/ml to 1×10-6g/ml with a detection limit of 8×10-11g/ml. The effect of foreign substances was also studied. The method has been satisfactorily applied to the determination of acetaldehyde in waste water. |
