摘要
本文采用高效液相色谱法,以庚磺酸钠-乙腈-缓冲溶液为流动相,使用以ZORBAXSB-C_(18)、5μm为填料的不锈钢柱和二极管阵列检测器,在290nm波长下对敌草快水剂中隐性成分百草枯进行筛查。结果表明,在15～400mg/L范围内,百草枯和敌草快线性关系良好,线性相关系数R^2均为0.999 9,相对标准偏差为0.67%和0.44%,平均回收率为99.64%和99.70%。
A method for screening of Paraquat in Diquat aqueous solution （AS） was developed by HPLC with Sodium heptane and acetonitrile buffer solution as mobile phase, ZORBAX SB - C18 DAD at 290nm wavelength. The result showed that the good linearity were obtained in the range of 15 - 400mg/L with the correlation coefficient of 0. 999 9. The relative standard deviation of 0. 67% and 0. 44%, the average recovery of 99.64% and 99.70% were obtained for paraquat and diquat respectively.
