摘  要:
采用高效液相色谱法建立了13种磺酰脲类除草剂的同时测定方法。采用ZORBAX SB-C18柱,以乙腈-磷酸水溶液为流动相进行梯度洗脱分离,采用二极管阵列检测器在230nm检测波长下进行检测和外标法定量。13种磺酰脲类除草剂在10~400mg/L范围内线性良好,相关系数为0.9990~0.9999;方法的平均添加回收率在99.2%~101.0%之间,相对标准偏差在0.11%~1.43%之间。

摘  要:
A method was developed for simultaneous determination of 13 sulfonylurea herbicides,which were separated on ZORBAX SB-C18 by HPLC with photodiode array detector,using the mixture of acetonitrile and aqueous phosphoric acid solution as mobile phase. The chromatographic separation and detection was performed by gradient elution at a wavelength of 230 nm and their quantitative determination by external standard method. The 13 sulfonylurea herbicides were measured in good linearity at 10-400 mg/L,and the correlation coefficients were 0.999 0-0.999 9. The average recoveries were in range of 99.2-101.0% with relative standard deviations of 0.11-1.43%.
