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.
