去年年底,中科院上海有机化学研究所和上海科学技术大学研究试制了环境分析标准品——直链烷基苯磺酸钠(简称LAS)。直键烷基苯磺酸钠是环境污染物监测分析的重要标准品之一。世界各国都把水中阴离子洗涤剂列入监测项目,我国饮水水质卫生标准规定也列为23个监测 Late last year, the Chinese Academy of Sciences Shanghai Institute of Organic Chemistry and Shanghai University of Science and Technology trial production of environmental standards - linear alkyl benzene sulfonate (LAS). Sodium straight alkyl benzene sulfonate is one of the important standards for the monitoring and analysis of environmental pollutants. In all countries in the world, anionic anionic detergents are included in the monitoring project. The sanitary standards for drinking water quality in our country are also listed as 23 monitoring
