摘要
应用循环伏安法测定了离子液体中硝基苯的扩散系数。硝基苯在离子液体中电还原,其扩散系数受硝基苯、离子液体及水的相互作用影响,随内外条件变化呈现复杂的变化规律。随硝基苯浓度增加扩散系数减小;相同硝基苯浓度时,水的浓度增加扩散系数增大;随着温度升高硝基苯扩散系数增大。
The diffusion coefficient of nitrobenzene electrochemical reduction in EMimBF4 was investigated by cyclic voltammetry. The results show that the interaction between EMimBF4, nitrobenzene and water has complicated effect on diffusion coefficient. With increasing of nitrobenzene concentration in EMimBF4, the diffusion coefficient decreases. When nitrobenzene concentration is same, with increasing of temperature and water concentration , the diffusion coefficient increases.
