Abstract

Attempts have been made to electrowin smooth and compact lead deposits from a medium containing glycine and hydrochloric acid, since this solution was recommended for its capacity to dissolve lead salts. Numerous factors such as electrolyte composition, current density, temperature, stirring and working electrodes were considered in the search for better quality deposits. Linear and cyclic sweep voltammetry, and potentiostatic and galvanostatic perturbations were employed in order to examine the processes at the cathode and to interpret the influence of some organic compounds added to the bath. Surface analyses of the lead deposit were performed by X-ray diffraction, scanning electron microscopy and Auger electron spectroscopy.
