| 摘 要： | 环境水体中的嘧磺隆在ｐＨ＝２－３的Ｈ２ＳＯ４介质中用二氯甲烷萃取富集，然后用高压液相色谱法分离和紫外光（２５４ｎｍ）检测器检测，外标法定量。用此方法测定了井水和生产单位排放的综合污水中的嘧磺隆，结果满意，最大相对标准偏差为５％，样品加标回收率在９３～１０７％之间，最低检测限量为２ｎｇ，最低检出浓度为０．００４ｍｇ／Ｌ。

| Abstract: | Sulfometron methyl in water samples can be extralted by dichloromethane in pH=2-3 of H2SO4 medium.It can be then separated with high pressure liquid chromatography and be determined with 254um wavelength of U V- spectrophotomctry.The method be used to determination of sulfometron methyl in well water and wastewater with 5% of maximum relative stanbard deviation and 93% to 107% of recovery ratioes.The method minimum detectability is 2ng and minimum detection concentration is 0.004mg/L. |
