Abstract: A method was developed to determine residue of phoxim in wheat and soil by HPLC.The lowest detection limit of instrument for phoxim was 0.5 ng.The average recovery of wheat and soil samples at the spiked amount of 0.02,0.2,2.0 mg/kg was 89.8%-98.9%,and the coefficient of variation was 0.8%-5.7%,the lowest detectable concentrations of various samples were 0.02 mg/kg.The average recovery of plant samples at the spiked amount of 0.04,0.4,2.0 mg/kg was 89.7%-95.8%,and the coefficient of variation was 0.5%-5.9%,the lowest detectable concentration was 0.04 mg/kg.This method proved sensitive,accurate and precise for pesticide residue analysis.
