Abstract

Lead ion gives a well-defined wave with $E_{1/2}$=-0.57V(vs. S.C.E.) from a base electrolyte consisting of 0.1M TEA=0.5M$KNO_3$=0.0002% methl red. (pH 9.8).The reduction wave of lead is lead(II) to lead(0) and electrode reaction of this wave diffusion controlled.Its diffusion current constant is 2.45 and temperature coefficient of this wave is about 1.2%.Under above conditions, diffusion current is proportional to the concentration of lead in the range of $10^{-3}$ ~$10^{-4}$ M.
