The Anodic Dissolution of Molybdenum
Corrosion, 1970The anodic dissolution of Mo was studied in H2SO4-K2SO4 solutions (pH = 0.4-3.4) and K2SO4-K2CO3-KOH solutions (pH = 9.5-13.6) at 25 C (77 F). Faradaic efficiency studies showed the metal to be electrochemically oxidized to the Mo-VI state. Analysis of surface films and polarization measurements indicate the corrosion resistance of Mo to be due to a ...

Anodic dissolution of liquid gallium
Electrochimica Acta, 1964Abstract The dissolution rate of liquid gallium anodes in 1 N solutions of hydrochloric acid, sulphuric acid and sodium hydroxide at 30·5°C has been measured radiochemically under galvanostatic conditions (0–12 mA/cm 2 ). In the hydrochloric acid solution, the anodes consume very nearly 2 F /g-atom gallium dissolved.

Anodic dissolution of adsorbed hydrogen
Transactions of the Faraday Society, 1966Hydrogen adsorption isotherms have been determined on catalyzed carbon electrodes. Curves similar to the Freundlich isotherm were obtained and at atmospheric pressure 4 ml g–1 of dry hydrogen was adsorbed, but when the electrode was wetted with potassium hydroxide solution the adsorption increased to a total of 14.0 ml g–1.

Electroinitiated cationic polymerization by anodic dissolution
Die Makromolekulare Chemie, 1988AbstractThe polymerization of several monomers, such as styrene, α‐methylstyrene, lactones, isobutyl vinyl ether, and hexamethylcyclotrisiloxane, was carried out in H‐shaped cells equipped with sacrificial anodes. The solvents, dichloromethane or nitromethane, contained tetrabutylammonium perchlorate playing the role of supporting electrolyte.

Anodic dissolution of tin in alcohols
Russian Chemical Bulletin, 2016Tin(II) alcoholates Sn(OR)2 are formed upon the anodic galvanostatic dissolution of tin in alcohols in an undivided cell in the presence of minimum amounts of NaOAc as an electrolyte. Tin(II) alcoholates are easily hydrolyzed in air to form oxyhydroxide Sn3O2(OН)2 used as an anode or its composite component in lithium cells.

Anodic dissolution of palladium + copper alloys
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1984Anodic dissolution of 50–83 at% Cu containing Pd+Cu alloy sheets were examined by constant current polarization and linear sweep voltammetry. One of the four ordered structures (PdCu3) described earlier could be identified by both electrochemical and X-ray diffraction methods.

The Anodic Dissolution of Binary Alloys
Journal of The Electrochemical Society, 1962A method for calculating the anodic polarization curves of binary alloys from those of their components is presented. Heterogeneous alloys can be treated as simple galvanic couples, but homogeneous alloys are subject to a modification of Tammann's concept of surface enrichment.

Anodic dissolution of copper(II) sulphide
Surface Technology, 1981Abstract The anodic behaviour of CuS in hydrochloric acid medium was studied. The observed active-passive type of behaviour could be principally due to the formation of elemental sulphur coupled with the pore diffusion model and/or to some stoichiometric changes at the effective electrode-electrolyte interface.

Dissolution kinetics of copper sulphide anodes
Hydrometallurgy, 1977Abstract Constant current and voltammetric experiments were carried out with synthetic and natural chalcocite and synthetic digenite anodes in a variety of electrolytes. Rapid dissolution of copper occurred at low potentials until limited by the rate at which copper could be transported from the reaction zone by diffusion through electrolyte held ...

Grain-dependent anodic dissolution of iron
Electrochimica Acta, 2007The influence of different dissolution techniques (electropolishing or chemical polishing and electrochemical machining (ECM)) on the topography of grains and grain boundaries of polycrystalline iron was analyzed by a combination of electron backscatter diffraction (EBSD) and contact-mode AFM. For electrochemical dissolution at large current densities,
