An ultrasonic decomposition of synthetic wastewater containing methanidophos is reported.The effects of power intensity, irradiation time, solution temperature, initial PH, Fe²⁺ and H₂O₂ concentrations on the decomposition of methamidophos have been examined.Under the conditions of initial concentration of methamidophos 0.5-5.0×10^-4mol/L, PH=2.5-10.8, 30℃, power intensity 80W/cm², Fe²⁺ concentration 50 mg/L in 2 h from the oxygen saturated sample solution 99.2% of methamidophos were decomposed according to the COD measurement results.
