本文研究了在微酸性介质中,磺胺或对氨基苯乙酮与NO_2~-离子重氮化反应的实验条件。建立了一个灵敏、快速测定NO_2~-的分析方法,大量NO_3~-存在不干扰测定。
In this paper, the experimental conditions of diazotization of sulfonamides or p - aminoacetophenones with NO_2 - ions in slightly acidic medium were studied. A sensitive and rapid method for the determination of NO 2 - was established. The presence of a large amount of NO 3 - did not interfere with the determination.
