Sažetak
The composition and characteristics of a new supporting electrolyte for the polarographic determination of small amounts of lead are described. The electrolyte is a 0.5 N aqueous solution of succinic acid containing 0.008 % gelatine. The analysis of the results obtained with this electrolyte shows that it can be used even when concentrations of the order of 10-6 M Pb (or 1 ug Pb/ml.) are involved. It has been shown that the electrode reaction consists in a reversible cathodic reduction of bivalent lead ions to the uncharged metallic lead.
