为了检测水中阿维菌素、多拉菌素、伊维菌素和甲氨基阿维菌素残留,试验采用液相微萃取提取、净化,高效液相色谱检测,样品过膜,经液相微萃取提取、净化后吹干,衍生化,高效液相色谱分析。结果表明:在0.05~2.0μg/L范围内呈线性,相关系数(r~2)≥0.999;方法的检测限为0.05μg/L,在0.05~2.0μg/L范围内回收率在87.53%~114.97%之间,日内变异系数在1.81%~4.57%(n=5)之间,日间变异系数在2.46%~6.10%(n=3)之间。
In order to detect avermectin, doramectin, ivermectin and emamectin residues in water, the test using liquid microextraction extraction, purification, high performance liquid chromatography detection, the sample membrane, the liquid micro Extraction and extraction, purifying, drying, derivatization, high performance liquid chromatography. The results showed that the detection limit was 0.05μg / L in the range of 0.05-2.0μg / L and the correlation coefficient (r ~ 2) ≥0.999. The detection limit was 0.05μg / L in the range of 0.05-2.0μg / L, and the recovery was 87.53% 114.97%. The coefficient of variation between days ranged from 1.81% to 4.57% (n = 5), and the coefficient of variation between days ranged from 2.46% to 6.10% (n = 3).
