本文用示波极谱法测定了 Ce(Ⅳ)-As(Ⅲ)-Ⅰ~-体系的反应级数,表观反应速率常数和表观反应活化能。建立了反应速率方程,对该反应体系的反应机理进行了研究,并用稳态处理法证明所提出的机理与实验结果完全一致。
In this paper, the reaction order, apparent reaction rate constant and apparent activation energy of Ce (Ⅳ) -As (Ⅲ) -Ⅰ ~ - system were determined by oscillopolarography. The reaction rate equation was established and the reaction mechanism of the reaction system was studied. The steady state method was used to prove that the proposed mechanism is in good agreement with the experimental results.
