利用反相高效液相色谱-荧光法分析测定土壤、甘蓝中甲氨基阿维菌素苯甲酸盐的残留量。甲氨基阿维菌素苯甲酸盐在10~500 ng/ml(r=0.999 6)范围内峰面积与进样量呈良好的线性关系,平均回收率甘蓝为95.61%,变异系数为0.4%;土壤中为81.4%,变异系数为4.9%。该法操作简便、快速,回收率较高。 The residues of emamectin benzoate in soil and cabbage were determined by reversed-phase high performance liquid chromatography-fluorescence spectrometry. The peak area of ​​the emamectin benzoate in the range of 10-500 ng / ml (r = 0.999 6) showed a good linear relationship with the injection volume. The average recovery was 95.61% for cabbage and the coefficient of variation was 0.4% ; 81.4% of the soil, the coefficient of variation of 4.9%. The method is simple, fast, high recovery rate.
