The electrodeposition and subsequent stripping of lead and cadmium on an indium tin oxide (ITO) optically transparent electrode (OTE) were monitored by attenuated total internal reflectance. Light passing through the ITO-OTE is attenuated proportionally to the concentration of metal ion and depositi...
