摘要
本文采用流动注射分析技术在线测定水中阴离子表面活性剂,使用的仪器为德国BRAN+LUEBBE公司自动分析仪。方法在0.050～0.400mg/L范围内,可以获得较好的线性方程,相关系数>0.9990,检出限为0.015mg/L,水样的回收率在92%～109%,此方法符合水质测定阴离子表面活性剂的要求。并对影响阴离子表面活性剂测定的因素进行探讨。
This study adopts Flow Injection Analysis for online determination of the Anionic Surfaetant in water. The autoanalyzer made by Bran ＋ Luebbe corporation in Germany was applied for determination. In the range of 0. 050 - 0. 400 mg/L, it is available to get good linear equations with correlation coefficient 〉 0, 9990, detection limit of 0. 015 mg/L and water samples recovery of 92% - 109%. This method meets the requirement of determining anionic surfactant for water quality control. The factors affecting the determination of anionic surfactant are discussed as well.
