Abstract: | [Objective] A method was developed to determine residue of Fenoxaprop-P in soil,wheat straw and grain.[Method] Residue of Fenoxaprop-P in soil,wheat straw and grain was studied by HPLC.[Result] 'The limit of detection(LOD) was 2 × 10-9g and limit of quantification(LOQ) in soil,wheat straw and gain were 0.005,0.025 and 0.010 mg/kg.The mean recovery and related standard deviation (RSD) of this method in soil,wheat straw and grain were 83.0%-89.8% and 4.4%-8.8%,93.1%-108.3% and 2.5%-14.8%,84.7%-96.6% and 4.4%-8.5% respectively.[Conclusion] it was an effective method which attained the pesticide residue analysis demands in sensitivity,accuracy and precision. |
