摘要
在5～15℃和加入无机盐的条件下,用二氯甲烷萃取、气相色谱内标法进行工业废水中环丁砜的测定。结果表明,方法检测限0.5mg/L,线性范围0～2g/L,变异系数<3%,标准加入回收率97.3%～102%。方法具有干扰小,测定时间短、结果可靠的优点。
At the conditions of temperature 5 ～15 ℃ and addition of inorganic salt,dichloromethane extraction and gas phase chromatogram internal standard are used to detect sulfolane in the industrial waste water.Result shows the detection limit of the method is 0.5 mg/L,linear range is 0～2 g/L,variation coefficient is <3%,standard addition recovery is 97.3%～102%.This method has the merits such as little interfere,short detection time and reliable results.
