A direct polarographic method is described for the simultaneous determination of from 10 to 200 ppm each of tin and lead in zirconium and Zirconium MV/ATR (an alloy containing 0.5% each of copper and molybdenum). The height of the single polarographic wave produced by the combined effect of lead and tin is measured, the diffusion current produced by lead is then suppressed by co-precipitating lead as sulphate, and the resulting wave height produced by tin alone is measured. Interference from copper and molybdenum is prevented by precipitating these elements as ferrocyanides. The method is simple and rapid and should be applicable to many different metallurgical materials. (auth)
