Abstract: 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 theinterference of foreign ions were discussed.The linear range was 1? 10-7 to 5 ? 10-6mol/L for lead.

Key words: lead, redtictive stripping potentiometry, potassium ferrocyanide, platinum elec-trode
