| 摘 要： | 建立了索氏提取、中性氧化铝小柱净化、高效液相色谱二极管阵列检测器测定土壤中7种三嗪类除草剂的方法，优化了检测波长、提取方法和溶剂、梯度淋洗程序等试验条件。7种三嗪类除草剂在0．10mg／L～2．00mg／L范围内线性良好，检出限为0．84μg／kg～2．07μg／kg，RSD为1．2％～5．6％，加标回收率为95.0％～107％。

| Abstract: | A HPLC with PDAD, soxlet extraction and neutral alumina clean up cartridge method was established for the simultaneous determination of seven triazine herbicides in the soil. The detection wavelength, solvent and extraction methods, procedures of gradient leaching were optimized. The good linearities of the 7 triazine herbicides were achieved in 0. 10 mg/L - 2. 00 mg/L. The detection limits were 0. 84 μg/kg - 2.07 μg/kg, RSD 1.2% -5.6% , and the recoveries 95.0% - 107%. |
