The degradation of two organophosphorus pesticides, malathion and dimethoate, was conducted in celery cabbage. The influence of the concentration of ozonated water, ozone action mode and degradation time were discussed. The two organophosphorus pesticides could be degradated over 70% in 30min by bubbling ozone. Detergent, rice water and ultrasonic were also employed to remove malathion and dimethoate in celery cabbage. The sequence of degradation efficiency was as following: bubbling ozone >; detergent >; rice water >; ultrasonic >; water. Bubbling ozone was the best way to degradate organophosphorus pesticides in celery cabbage. The residues were extracted by solid phase microextraction and detected by gas chromatography with flame photometric detector.
