The reductive stripping potentiometric analysis of lead in the presence of potassi-um ferrocyanide as reducing agent on platinum electrode has been investigated. The pretreat-ment of the electrode, processes of anodic preconcentration and subsquent analysis,and the interference of foreign ions were discussed. The linear range was 1×10^-7 to 5×10^-6 mol/L for lead.
