Abstract
A water-soluble polyelectrolyte, polyhexamethyleneguanidine, inhibited copper(II) and cadmium(II) discharge on a static mercury drop electro de. The effect was due to adsorption of the polymer on the mercury and depended to a large degree on pH. Addition of chloride to the solutio n increased the inhibition, by the positively charged polyelectrolyte, of copper(II) discharge through concurrent adsorption of the anion an d polycation on the positive electrode. The data were used to develop a method for determining polyhexamethyleneguanidine in plating baths.
