INTERFACIAL ELECTRODEPOSITION OF SILVER

A systematic study of silver ion electrodeposition at the water/air an d water/dichloromethane interfaces, under potentiostatic control, is p resented. We study the morphology of the deposits and their growth rat e, as a function of several important physical and chemical parameters , namely, the electric voltage, the silver ion concentration, the cond uctivity, the viscosity, and the presence of a surfactant and an organ ic anionic additive known to associate with silver. The results are di scussed in terms of a generalized Wagner number, which is shown to cor relate well with the observations and to be a highly reliable predicti ve tool for the morphologies.
