前言在工业上,芳胺的用途广,尤其苯胺的用途更为广泛。在生产或使用芳胺的厂区、排出的废水中,或多或少地含有芳胺。芳胺化合物毒性很大,还具有致癌作用。在环保中,芳胺是一项重要的监测项目。测定芳胺的分光光度法中,共同点是用亚硝酸盐重氮化,然后用不同的偶合剂进行偶联显色测定。常用的偶合剂有:甲萘胺,亚硝基红盐,H 酸,盐酸萘乙二胺等,而以后者为流行。我们所研究的方法是α-萘酚法,此 Preface In the industry, aromatic amine wide range of uses, especially the use of aniline more widely. In the production or use of aromatic amine plant, the discharge of waste water, contain more or less aromatic amines. Aromatic amine compounds are highly toxic and have carcinogenic effects. In environmental protection, aromatic amine is an important monitoring project. Spectrophotometric determination of aromatic amines, the common point is to use nitrite diazotization, and then use different coupling agent for coupling color determination. Coupling agents commonly used are: melamine, nitrosyl red salt, H acid, naphthyl ethylenediamine hydrochloride, etc., while the latter is popular. Our research method is α-naphthol method, this
