摘　　要：离子液体溶剂浮选荞麦汁中的4种三嗪除草剂,包括草净津、敌草净、密草通、特丁津。用高效液相色谱法对分离的物质进行测定,研究浮选过程中试验参数的影响。在优化的试验条件下,方法在0.100~2.000 mg/L内线性良好,检出限为0.7μg/L,应用于荞麦汁样品的分析,平均回收率为85.2%~102.1%,相对标准偏差均小于4.0%。The four triazine herbicides in buckwheat juice were extracted and separated by using ionic liquid solvent flotation.High performance liquid chromatography(HPLC)was used to determine the separated substances.Under the optimized experimental conditions,the method has a good linearity in the range of 0.100~2.000 mg/L,and the detection limit was 0.07 mg/L.When applied to the analysis of buckwheat juice samples,the average recoveries were 85.2%~102.1%,and the relative standard deviation was less than 4.0%.
