Abstract
In situ formation of a film with alkyl and lead from Pb(NO3)(2) over carbon paste electrodes was electrochemically studied. Thr experiments were carri ed out at two pH values (3.06 and 6.65) using acetate buffer (CH3COOH/CH3CO ONa) as supporting electrolyte. It was found that at both pH values time al kyl and lead species are formed in agreement with IR-ATR and SEM with x-ray probe experiments of the film over ITO. At pH 6.65 a stable film is formed .
