摘要
采用高效液相色谱法连续测定吡虫啉和多效唑的含量,该方法中吡虫啉和多效唑标准偏差分别为0.94和0.59,变异系数为0.58%和0.45%,在0 8～15 0mg/L和1 5～25mg/L的范围内与峰高呈良好的线性关系,回收率为99 6%和98 9%,其相关线性系数为0 9995和0 9989,满足在水样、秧苗、稻谷样品中的检测要求,方法简便、快速、准确。
A method for continuous determination of imidacloprid and paclobutrazol is described by high performance liquid chromatography. A baseline resolution of imidacloprid and paclobutrazol with impurities was achieved on Bondapak C_(18) column within 12 min by using methanol-water system (70∶30 by voiume) as a mobile phase at flow rate of 1ml/min, and the eluate was monitored at λ=254nm. Imidacloprid and paclobutrazol in the liner range of 0.8～15.0mg/L and 1.5～25mg/L has a good linearity with its high (r=0.9995 and r=0.9989). The RSDs 0.58% and 0.41%, recoveries 99.6% and 98.9% for the method were obtained.
