The voltammetric polarization of Cu specimens in Na,CO" NaHCO, and NaCIO, solutions (8-12 pH range) has been investigated . Voltammetry data were complemented with SEM and electron microprobe analysis . Results are found to be in agreement with the passivation model developed for Cu in plain NaOH so
The anodic dissolution of W in NaOH solutions of pH 13-14 has been studied . The opencircuit potential becomes more noble with time up to a period of about 15 h ; thereafter it remains constant . The Tafel slope of the current/potential curves is the same regardless of pre-treatment of the electrode
Abstrad-Methyl viologen (MV++) is incorporated into a xeolite modified carbon paste electrode (ZMCPE). The electrochemical behaviour of MV++ is examined in aqueous medii with various supporting electrolytes (NaCl, NaBr and several tetraalkylammonium bromides) by cyclic VoltammeWy, chronoamperometry
