摘　　要：通常情况下,阴离子合成洗涤剂会在各类水环境中广泛存在,属于生物难降解物质,其既会对水生生物及环境具有一定危害性,也会影响生活饮用水质量。如果人们通过饮用水将其摄入后,就会对人体产生轻微毒性,导致血液总胆固醇增高,血红蛋白、红/白细胞的数量和水平发生变化。因此,这也是生活饮用水质量重要监测指标之一。本文利用亚甲蓝分光光度法测定生活饮用水,采用比色管和分液漏斗精制分离的方法测量其吸光度,测定、分析生活饮用水中阴离子合成洗涤剂,发现在0.05~1.00 mg/L范围内线性关系良好,且加标回收率在97.4%~106.3%。但水中游离氯的含量会对该测定方法有一定负干扰,所以,在实际检测过程中需重点关注这一干扰因素。In general,anionic synthetic detergents exist widely in all kinds of water environments, which are hard to be degraded by organisms,it will not only harm aquatic organisms and the environment, but also affect the quality of drinking water.If people consume it through drinking water, it will produce slight toxicity to the human body, resulting in increased total blood cholesterol, changes in the number and level of hemoglobin and red/white blood cells.Therefore, it is also one of the important indicators for monitoring the quality of drinking water.In this paper, methylene blue was used to determine drinking water, the absorbency of drinking water was measured by colorimetric Tube and separation funnel, and the anion synthetic detergent in drinking water was determined and analyzed, the linear relationship was found to be good in the range of 0.05~1.00 mg/l, and the recoveries were 97.4%~106.3%.However, the content offree chlorine in water has some negative interference to the determination method,therefore, we should pay attention to this interference factor in the actual detection process.
