摘要

利用伏安法和阻抗法研究了 ACT-CTAB 和 ACT-SDS 混合吸附层对 In(III) 离子电还原动力学和机理的影响。研究表明,乙酰唑胺(ACT)催化了电极反应过程(根据盖对规则)。在所研究的每个体系中,In(III) 离子电还原过程都具有多步骤性质,其中在吸附层中形成活性 In(III) - ACT 复合物的化学步骤发挥了重要作用。阳离子表面活性剂 CTAB 的存在增加了 ACT 加速 In(III) 离子电还原过程的动力,而阴离子表面活性剂 SDS 的存在则抑制了这一反应。

Electrochemical Measurements of the In(III) Ions Electroreduction; the Influence of Mixed Adsorption Layers ACT-CTAB and ACT-SDS
Using voltammetric and impedance methods, the effects of mixed adsorption layers ACT-CTAB and ACT-SDS on the kinetics and mechanism of In(III) ions electroreduction were investigated. Acetazolamide (ACT) was shown to catalyse the course of the electrode reaction (according to the cap-pair rule). The multi-step nature of the In(III) ions electroreduction process in each of the systems studied in the chemical step of formation of the active In(III) - ACT complexes in the adsorption layer playing an important role is demonstrated. The presence of the cationic surfactant CTAB increases the dynamics of acceleration of the In(III) ion electroreduction process by ACT, while the presence of the anionic surfactant SDS inhibits this reaction.
