本文研究酸性染料溴甲酚紫的液/液界面离子传输过程。详细研究了两相基础电解质对传输过程的影响,用离子缔合的观点解释了传输电位与有机相基础电解质浓度的关系。探讨了有机相溶剂性质对传输电位的影响,讨论了传输机理,并用光谱方法进行了验证。实验所测半波电位△_0~wφ_(1/2)-pH曲线与根据传输机理推导的方程式相符合,计算了传输离子的标准传输电位△_0~wφ°和标准Gibbs传输能△_0~wG°。
In this paper, the acid / liquid bromine cresyl violet liquid / liquid interface ion transport process. The influence of the two-phase basic electrolyte on the transport process was studied in detail. The relationship between the transport potential and the basic electrolyte concentration in the organic phase was explained from the viewpoint of ion association. The influence of the solvent property of organic phase on the transmission potential was discussed. The transmission mechanism was discussed and verified by spectral method. The half-wave potentials △ _0 ~ wφ_ (1/2) -pH measured by the experiment are in accordance with the equations derived from the transport mechanism, and the standard transfer potentials Δ_0 ~ wφ ° and the standard Gibbs transfer energies △ _0 ~ wG °.
