The electroreduction behavior of lead ions in aqueous solution of tetrafluoroboric acid on platinum electrode has been studied and investigated in this work. The cyclic voltammetry (CV) was used for studying the electrochemical reduction behavior of lead ions in certain conditions. The voltammetric responses of the investigated lead ions are found to be sen­si­tive to temperature as well as the scan rate in these conditions. Interesting data and para­meters were obtained and discussed in this work. The mechanism of the elec­trochemical reduction of lead at the optimal conditions on the electrode surface of platinum has been evaluated and proposed.
