摘要: 油/水界面上的电化学研究是近年来电化学研究中的一个新领域[1],对膜电化学的发展具有重要意义。目前研究油/水界面电化学中普遍使用循环伏安(CV)法[2]和循环线扫电流计时电位(CLC)法[3]。有关抗生素在油/水界面的转移已有报导[4-8],本文用CLC法和CV法对肌肉松弛剂季铵酚离子在水/硝基苯界面的转移行为进行了研究。

Abstract: The ion transfer of the muscle relaxing agent gallamine triethiodide across tbe water/nitrobenzene interface was studied by cyclic voltammetry and chronopotentiometry with linear current scanning. The calculated standard interfacial potential difference, Gibbs free energy, and partition coefficient of gallamine triethiodide in two phases were △owφ0=0.22V, △owGo=-8.1kJ and kp=0.65, respectively. The linear relationship between peak current and concentration of gallamine triethiodide could be used for medicinal analysis.
