Specific adsorption on platinum electrode of chloride melts with nickel and cobalt complexes

摘要

Two kinds of adsorption of chloride complexes on platinum were shown to be caused by a ratio of the complexes' strength to the interaction energy of Pt surface with chlorine anion. The non-dissociated bulk complex of nickel is laced in the diffuse part of double electric layer (DEL) keeping constant the initial values of capacity, zero charge potential and the charge of highly dense DEL pt~δ+ -Cl~δ-. The less strong and bulky complex of cobalt can be introduced into DEL to form heterophaseous complexes of Pt~δ+ -Cl~δ- -Co~2+ type changing essentially the values of capacity, potential and charge.
