Abstract :
The ozonation of three organ phosphorus pesticides, malathion, diazinon and dimethoate, was conducted in water. The influence of the concentration of ozonated water, ozone action mode, degradation time and ion scavenger was discussed. The three organ phosphorus pesticides could bed gradated completely in 15min by bubbling ozone in water. And additional ion scavengers could increase the degradation ratio. The residues were extracted by solid phase micro extraction and detected by gas chromatography with flame photometric detector.
