摘要
提出了一种同时测定甲基托布津和扑海因的高效液相色谱法。方法的线性范围、相对标准偏差和检测限分别为 :甲基托布津 :1 .0～ 40 .0mg L ,0 .7% ,1 .0mg L;扑海因 :0 .2 5～ 1 2 5 .0mg L,0 .6% ,0 .2 5mg L。本方法用于保鲜剂中扑海因和甲基托布津含量及甜瓜中残留量的测定 ,取得了很好的结果。
In this paper, we report a high performance liquid chromatographic method for the simultaneous determination of thiophanate-methyl and iprodione. The linear range of the method, relative standard deviation and the detection limit are 0.25 similar to 125.0 mg/L, 0.6%, 0.25 mg/L for iprodione and 1.0.similar to 40.0 mg/L, 0.7%, 1.0 mg/L for thiophanate-methyl, respectively. The method has been applied to the determination of thiophanate-methyl and iprodione in the preservative agents and muskmelons with satisfactory results. The method is simple and fast.
