Xiang ying analysis technology co., LTD XiangyingGC7990plus gas chromatography method is used to detect life drinking water of epoxy chloropropane, measured components can ensure the chromatographic peak of chromatographic peak of epoxy chloropropane and other components of separating degree meet the requirements of gas chromatography determination. Format, gas chromatography. Epichlorohydrin determination of the lower limit of 0.1 mu g/L, below in the "drinking water health standards" GB5749-2006 epoxy chloropropane products limit is 0.4 mu g/L, satisfying the requirements of domestic and drinking water hygiene determine. Linear regression equation is good, meet environmental monitoring industry gas chromatographic determination of the linear correlation coefficient is not smaller than 0.995. Recovery was 83.8% ~ 83.8% to meet the environmental monitoring industry gas chromatographic determination of recovery is not less than 70% ~ 130%. Relative standard deviation is 3.0% ~ 3.0%, the deviation is smaller. The purge and trap method before drinking water treatment, safety and health, easy to operate, save time and effort, determination of fast. To sum up, this method for the determination of epichlorohydrin in domestic and drinking water.
环氧氯丙烷是一种重要的有机化工原料和精细化工产品,用途十分广泛。根据国标GB/T 5750.8-2006的检验方法环氧氯丙烷的***限是0.02 mg/L(即0.02 mg/L),但国标GB5749-2006生活饮用水中环氧氯丙烷的限值是0.000 4 mg/L(即0.000 4 mg/L)。如果按国标的检验方法检测,不能判定。
滕州市翔鹰分析技术有限公司研究生活饮用水中环氧氯丙烷的检测方法,满足《生活饮用水卫生标准》的要求以及实际水质检测的需求。方法生活饮用水中环氧氯丙烷经过有机溶剂萃取,萃取液浓缩后,高弹石英毛细管柱分离,用XiangyingGC7990plus气相色谱仪测定。结果该方法RSD均10%,加标回收率为84.4%~105.4%,***检出限为0.000 2 mg/L。结论该方法比***方法中经过填充柱分离,用FID检测器检测生活饮用水中环氧氯丙烷灵敏度高,能满足《生活饮用水卫生标准》的要求以及实际水质检测的需求。
