摘要
研究了在微酸性溶液中，萘胺与对氨基苯乙酮的重氮盐在室温下，形成偶氮化合物的实验条件，建立了一个极其灵敏的快速测定ＮＯ_２~－的新方法。在２０×１０^（－１０）～１．０×１０^（－８）ｇ／ｍＬ浓度范围内，峰高与ＮＯ_２~－离子浓度呈良好的线性关系。本方法用于直接测定水样中ＮＯ_２~－含量，获得满意结果。
in this paper,the optimum experimental conditions are studied for the formation of azo-compound of diazonium salt derived from paminoacetophenone and naphthylamine in acidic medium.A sensitive and quick method to determine nitrite has been established.The linear range is 2.0×10￣(-10)￣1.0×10￣(-8)g/ mL.Several water samples have been directly analyzed by the recommended procedure and a satisfactory result was obtained.
