摘要
在0.1mol·L^(-1)LiCl(w)——0.05mol·L^(-1)TPAsTPB(nb)体系中,采用四电极半微分循环伏要法,探讨了过氧化氢存在下FeCl_3(w)与FeCP_2(nb)电对在水/硝基苯界面的电子传递催化波的特性,所得半微分极谱峰良好,峰电流e,与Fe(Ⅲ)浓度成正比,与氧化剂过氧化氢浓度的平方根有线性关系.且通过对体系半积分曲线的对数分析,估算了有关常数。
The electron transfer between FeCl3 and ferronece redox couples across a water/nitrobenzene interface catalyzed by H2O2 has been invertigated by using semi - integral and semidifferential cyclic voltammetry. In the electron transfer system of 0. 1 mol/1 LiCl, FeCl3, 0. 01mol/1 H2O2(W) - 0.005 mol/1 TPAsTPB, 0.05 mol/1 ferronece(NB), a good catalytic wave appeared. The semi - differential peak current (ep) was directly proportional to the concetration of Fe( Ⅲ and to the square root of the concentration of hydrogen peroxide(w). Same parameters were estimated by the semi - integral curve and its logarithmic analysis.
