摘　　要：抑快净由霜脲氰及恶唑菌酮混配而成。本试验采用高效液相色谱(HPLC)法,对52.5%抑快净水分散粒剂中霜脲氰及恶唑菌酮在番茄中的残留进行检测分析。结果表明在0.01~1.0 mg/kg范围内,番茄中霜脲氰的平均回收率为79.5%~92.8%,相对标准偏差为3.68%~7.36%;在0.01~2.0 mg/kg范围内,番茄中恶唑菌酮的平均回收率为82.4%~103.9%,相对标准偏差为2.96%~6.25%。该方法的准确性、精确性以及灵敏度均达到农药残留分析的要求。霜脲氰和恶唑菌酮在番茄中的消解动态均符合一级动力学特征,并且恶唑菌酮的降解速率快于霜脲氰。霜脲氰和恶唑菌酮在番茄中的最终残留量符合我国最大残留限量标准。Equation-pro is a mixture of cymoxanil and famoxadone.In this experiment,HPLC method was used to detect and analyze the residues of cymoxanil and famoxadone from 52.5%equation-pro WG in tomato.The results showed that in the range of 0.01~1.0 mg/kg,the average recoveries of cymoxanil in tomato were 79.5%~92.8%with the relative standard deviation(RSD)of 3.68%~7.36%.In the range of 0.01~2.0 mg/kg,the average recoveries of famoxadone in tomato were 82.4%~103.9%with the RSD of 2.96%~6.25%.The accuracy,precision and sensitivity of this method could meet the requirements of pesticide residue analysis.The degration dynamics of cymoxanil and famoxadone in tomato accorded with the firstorder kinetic characteristics,and the degradation rate of famoxadone was larger than that of cymoxanil.The final residues of cymoxanil and famoxadone in tomato accorded with the maximum residue limit standard(MRL)of China.
