摘　　要：采用光度分析的工作曲线准确测定2-重氮-1-萘醌-5-磺酰氯的含量。于丙酮和无水乙醇的混合溶剂中，波长为380nm，该物质在4～30μLg/ml内与吸光度成直线关系。相关系数为0．9999，平均回收率100.24％，相对标准偏差为0.53%。The content of 2-diazo-1-naphthoquinones- chloride was deternened by absorption linemethod of spectrometric anaysis at 380nm using acetone and anhydrous ethtl alcohol as the solveng Inthe range of 4-30ug/ml there existed a good linear relationship between concentration and absorbance Thecoffelative coefficient was 0.9999 The average rate of recovery and the reative standard deviation are100.24% and 0.53% respectively
