| 摘 要： | 本文报道一种极谱测定二苯胺的新方法,它是基于二苯胺引起的氧极谱催化波.这个氧极谱催化波是由于二苯胺催化了电生超氧离子O_2~(-)的歧化反应产生的.本方法简单方便,有良好选择性.应用本方法测定了化工原料二苯胺的含量,结果令人满意.

| Abstract: | A new inethod for polarographic determination of diphenylamine (DPA ) was described on the basis of the cataly-tic wave of oxygen caused by DPA. Tins method was rather simple .convenient and selecnve.and in has been applied to determine DPA content in industrial raw male-rial. |
