摘要
以中性红(NR)为探针,根据表面活性剂的增溶作用,采用线性扫描吸附伏安法测定了十二烷基苯磺酸钠 (SDBS)的临界胶束浓度(CMC),并初步探讨了中性红在悬汞电极(HMDE)上的反应机理,测得电子转移数n为2, 电荷传递系数α为0.611.
Critical micelle concentration (CMC) of sodium dodecyl benzenesulfonate (SDBS) in aqueous solution has been determined by adsorption voltammetry using neutral red (NR) as a electroactive probe molecule. The mechanism of electrochemical reduction of NR at hanging mercury drop electrode (HMDE) has been explored, and also gives both the electron transfer number n and the charge transfer coefficients a as 2 and 0. 611, respectively.
