## Abstract The conditions for the preparation of PbO~2~ modified Pt rotation disc electrode in solutions containing HC10~4~ and Pb(II) were studied, and the morphology and composition of the obtained PbO~2~ film were characterized by SEM and XRD techniques, respectively. The results show that the
Electrochenucal methods were followed m the preparatron of a-and p-PbO, by super-"nposmg ac on dc. The samples obtained wtth dttferent proportrons of ac were analysed chemrcally, therm0 vunetrtcally and by X-ray d&a&on. In t!za e case of /I-PbO, the percentage ac supernnposed increases the formation
This work describes the study of underpotential deposition (upd) of Pb on polycrystalline platinum in 0.2 M HCIO, solutions using cyclic voltammetry and rotating ring-disk electrode techniques. In such conditions, a full monolayer of upd Pb corresponds to a coverage of 0.41. The adsorption of lead i
