摘要
建立了固相萃取-高效液相色谱测定水中7种磺酰脲类除草剂的方法,考察了降解作用及滤膜对测定的影响。方法在0.30 mg/L^5.00 mg/L之间线性关系良好,7种磺酰脲类除草剂的检出限为0.32μg/L^0.62μg/L,RSD为4.4%~7.6%,平均加标回收率为87.9%~102%。
The method was established for determination of 7 kinds of sulphur ureides herbicides by solid phase extraction-high effective liquid chromatography. The influence of degradation action and filters were observed. There were good linear relationships between the instrumental responds and compounds in range of 0.30 mg/L and 5.00 mg/L of the method. The detective limits of 7 kinds of sulphur ureides herbicides were 0.32 -μg/L - 0.62 μg/L, RSD 4.4% - 7.6% , avenge recoveries 87.9% - 102%.
