摘要
应用高效液相色谱进行分析虱螨脲在番茄、菜豆中的残留降解动态和最终残留。虱螨脲的最小检出量为2×10-9g,在番茄、菜豆中的最低检测限均为0.03mg/kg,在番茄、菜豆中的添加回收率分别为82.1%～101.8%和82.9%～102.5%,相对标准偏差分别为2.86%～9.08%和3.91%～8.87%。虱螨脲在番茄、菜豆中的降解符合一级动力学方程,半衰期分别为7.2、6.7d。
A study was undertaken to evaluate the dissipation of residues lufenuron in tomatoes and beans grown in open field.The lufenuron residues were determined by HPLC.The minimum detectable amount of the pesticide was 2×10-9 g and the value of limit of quantification was 0.03 mg/kg.The average recoveries were 82.1-101.8%for tomato and 82.9-102.5%for bean,with the corresponding RSD of 2.86-9.08%and 3.91-8.87%,respectively.The dissipation of lufenuron residues in the tomatoes or beans followed first-order kinetics...
