摘  要:目的:建立敌敌畏在蔬菜中的残留量的反相高效液相色谱(RP-HPLC)分析方法。方法:用Hypersil C18柱(120A,5μm,4.6mm×300mm)色谱柱,以甲醇-水为流动相,流速1.0ml/min,215nm检测。结果:敌敌畏在0.13~12.0mg/L范围内呈良好的线性关系,检出限为0.113mg/L,添加平均回收率为89.9%,RSD为1.87%。结论:RP-HPLC法简单、可靠,可应用于蔬菜中敌敌畏的残留量的测定。Objective: To establish a method for the determination of the residues of DDVP in vegetables. Methods: Reversed-phase high performance liquid chromatography was adopted. Hypersil C18 column (5μm, 4.6 mm × 300 mm ID)was used with CH3OH: H2O (65: 35,V/ V ) solution as mobile phase, and the flow speed was 1.0 ml/min. The ultraviolet detection wavelength was 215 nm. Results: Good linear correlation for DDVP was found in the concentration range of 0.13 - 12.0 g/L. The detection limit was 0.113 g/L for DDVP ( S/N = 3 ). The average recovery rate was 89.9 %, with RSD 1.87 % (n = 5) . Conclusions: This method is simple and reliable. It can be used for the determination of DDVP residues in vegetables with satisfactory results .
