Study and optimization of the detection methods for 10,10-Oxybisphenoxar-sine in plastic products by HPLC-DAD. Plastic sample was diluted in methanol and extracted by ultrasonic twice. The solution was then filtered through film. The mobile phase consisted of acetonitrile and water(v/v=70:30). Detection wavelength was set at 220 nm. The linear corre?lation coefficient was greater than or equal to 0.999 in concentration range of 0.25~10.0 mg/L. And the detection limit was 5.0 mg/kg. The recoveries of the standard working solution with various concentrations in blank samples were researched and the results are 82%~101%.
