Low carbon steel exhibits active–passive transition in buffered slightly acidic (pH 4–6) brines at various temperatures. The pH, the temperature and the concentration of chloride ions have significant effects on the active–passive behavior and

The anodic oxidation of sulfide ions from chloride brines at graphite electrodes is shown to produce elemental sulfur, that was identified using XPS and EDS measurements. The process is controlled by charge transfer at the interface and diffusion of

The polarization curves of low carbon steel in deaerated carbonate bicarbonate buffers (pH 10.3) show three distinct regions: (a) an active region characterized by a Tafel slope of 125 ± 5 mV which is independent of the chloride concentration, (b) a

Benzotriazole (BTAH) is shown to decrease the extent of localized corrosion of alpha brass in salt water contaminated by sulfide ions. The results are interpreted in terms of competitive adsorption of BTAH and sulfide ions on the brass surface and in

Packed bed electrodes, made of stacked screens, have been used as cathodes for the removal of lead ions from flowing alkaline electrolytes. We consider the coulombic efficiency ξ = i Pb / ( i Pb + i H ) , where i Pb and i H are, respectively, the le
