β¦ Synopsis
Abstracf-The anodic and cathodic polarization curves of bromine-active carbon electrode in the fused eutectic AgBr + KBr at 400-700Β°C have been determined by the galvanostatic method. The amount of adsorbed halogen has been calculated as a function of potential and interpreted on the basis of Langmuir-Temkin, isotherms. For coverages between 0.2 and 0.8 the Temkin isotherm is valid. A comparison of the behaviour of chlorine-, bromine-. iodine-active carbon electrodes in fused salts is given.

Polished glassy carbon electrodes were activated in either air at 400"-800Β°C or steam at 790"-980Β°C. Square wave voltammetry of air-activated electrodes in Mcllvaine buffer revealed the presence of a significant surface redox couple. Nernst plots of the peak potential vs. pH gave an average slope of
The role of electrode selectivity in the performance of the ferrous/thionine photogalvanic cell has been studied using various carbon materials as light electrode. The open-circuit voltage of the cell is found to depend strongly on the type of carbon electrode used. This dependency can be quantitati
