摘　　要：研究了亚硝基R盐在汞电极上的电化学行为和电极反应机理.结果表明:亚硝基R盐在汞电极上的电极反应为准可逆过程,电子转移数为4,其被还原为其相应的氨类化合物;吸附符合福兰克林吸附方程,吸附系数β=3.63×105L/mol,饱和吸附量sΓ=1.00×10-10mol/cm2,吸附因子υ=0.94.The electrochemical behavior of Nitroso R salt on mercury electrode was investigated,and the mechanism of the reaction was discussed. The experimental results indicate that Nitroso R salt （NRS） is reduced quasi-reversibly by a four-electron process to the corresponding hydroxylamine derivative. The adsorption of NRS on the mercury electrode obeys the Frumkin adsorption isotherm, and the adsorption coefficient （β= 3. 63 × 10^4 L/mol）, the amount of saturated adsorption （Гs = 1.00×10^（-10） mol/cm^2） and the attractive factor （v = 0. 94） are evaluated.
