| 中文摘要 | the adsorption of cationic surfactant cetylpyridinium bromide (cpb) on a glassy carbon (gc) electrode surface has been studied by spectroelectrochemistry with a long optical path length thin-layer cell (loptlc) for the first time. a fine adsorption isotherm of cpb molecules from an aqueous solution containing 0.10 m kbr has been obtained over the range of (1.00-8.00) x 10(-5) m. from theoretical calculation and experimental data, adsorption of cpb on the gc electrode surface shows four distinct orientations and three large orientation transitions. compared with the ordinary isotherm, the differential isotherm is more characteristic and would be suitable for the study of orientation transitions of organic compounds. with a theoretical treatment of the adsorption isotherm, four orientations of adsorbed cpb on a gc electrode surface coincide with the frumkin-langmuir type. from adsorption parameters the frumkin-langmuir equations, the adsorption free energy and, therefore, the equilibrium constants of orientation transitions of the cpb molecule can be obtained. |
