二苯胺磺酸钠,目前广用在化学分析上作灵敏的氧化还原指示剂,特别在钢鉄分析过程中应用更为普遍。它首先是在1931年被L.A.Sarver和I.M.Kalthaff所发现:应用作氧化还原指示剂的机理可用下列反应表示:
Sodium diphenylamine sulfonate, widely used in chemical analysis as a sensitive redox indicator, especially in steel 鉄 analysis process is more common. It was first discovered by L.A. Sarver and I.M. Kalthaff in 1931: The mechanism for use as a redox indicator can be represented by the following reaction:
