An analytical method has been devised for the determination of copper and lead in electrolytic tin and high purity selenium by square wave polarography. The mother elements were expelled, and the copper and lead were then determined simultaneously in HClO<SUB>4</SUB> supporting electrolyte.<BR>The proportionality between height of wave and concentration of copper and lead, and the effects of electrode distance, of superimposed voltage, of electrolyte temperature, of dissolved oxygen, and finally of coexistent elements were investigated; and from these results the optimum conditions were determined and the analytical method was established.<BR>Analytical values obtained by this method using samples of relatively small quantity (15g) agreed with those obtained by the dithizone method, and the time necessary for analysis was relatively short even for an operator having no special experience.
