- 摘要:
- 建立了反相高效液相色谱测定土壤中甲黄隆残留量的方法。 试验以甲醇∶水∶冰乙酸(60∶40∶1, 体积比)为流动相进行洗脱, 采用 C 18 柱分离,利用紫外检测器在 227nm 波长下检测。该方法在0.50~ 10.0mg·L -1 范围内呈良好线性, 相关系数为 0.9997, 检测限为0.005 mg·kg -1 , 方法的回收率为 86%~ 98%, 精密度为2.32%~ 4.04%, 用于土壤中甲黄隆残留检测效果良好
- Abstract:
- The high performance liquid chromatography method was developed for the determination of metsulfuron in soil.The chromatographic analysis was carriedout using the mobile phase consistedof methanol, water and acetic acid(60∶40∶1, v/ v), and the detection at 227 nm.The linear range was 0.50~ 10.0 mg·L -1 , and the detection limit was 0.005 mg·kg -1 ,spiked recoveries rate was 86%~ 98%, and the RSDs was 2.32%~ 4.04%.This method operated simple and detectioneffect of metsulfuron in soil was good.
