摘　　要：提出了分光光度法测定水中痕量甲萘胺的新方法。甲萘胺与对硝基重氮盐偶合成黄色的染料，在４７５ｎｍ处进行分光光度法测定。甲萘胺的浓度在１．０～２０．０ｍｇ／Ｌ时呈线性，检出限为１ｍｇ／Ｌ，回收率在９５．４％～１０５．２％。该法具有灵敏度高，对甲萘胺有较好的选择性等特点，用于水中痕量甲萘胺的测定，结果令人满意。new spectrophotometry for determination of trace α Naphythylamine in water is proposed.α Naphythylamine couples with p nitrodiazo salt to form yellow azo dye.At 475nm it is determinated by spectrophotometry.The calibration graph is linear for 1.0～20.0mg/L α Naphythylamine,the detection limit is 1.0mg/L, and the recovery is 95.4%～105.2% .The method is sensitive and selective.The α Naphythylamine in water has been determined with satisfactory results.
