| Abstract: | The analytical method for the determination of trifloxystrobin and tebuconazole residues in the husked rice,rice hulls,rice plant,soil and paddy water was developed based on ultra high performance liquid chromatography tandem mass spectrometry(UPLC-MS/MS).The results showed that the calibration curves for trifloxystrobin and tebuconazole were linear in the range of 0.001~0.032 mg/L with correlation coefficients of 0.9995 and 0.9998.When the spiked level ranged from 0.02 to 2 mg/kg,the average recoveries of trifloxystrobin and tebuconazole in husked rice,rice hulls,rice plant,soil and paddy water were in the range of 79%~109%,and the relative standard deviation(RSD)ranged from 2.3%to 8.5%.The limit of quantitation(LOQ)of trifloxystrobin and tebuconazole in all the matric was 0.02 mg/kg. |
