Elimination of sulfamethoxazole by anodic oxidation using mixed metal oxide anodes
Journal of Water Process Engineering, 2023The degradation of sulfamethoxazole (SMX) was studied by anodic oxidation (AO) process using mixed metal oxide (MMO) electrodes with different Ru/Ir ratios. Each electrode was characterized morphological and electrochemically. The electrolyzes were performed in NaCl and Na2SO4 applying two current densities (10 and 50 mA cm-2).

Anodizing is a low-temperature, low-cost electrochemical process allowing for the growth, on the surface of valve metals and valve metal alloys, of anodic oxides of tunable composition and properties. This article is an overview on theoretical aspects concerning the general aspects of the kinetics of growth of barrier and porous anodic oxides and some ...

Oxide anodes in electro-organic oxidation. Oxidation of maleic addon tungsten oxide anodes
Journal of Applied Electrochemistry, 1982The electrochemical oxidation of maleic acid on tungsten anodes has been investigated. Glyoxal and carbon dioxide were the main products together with tartaric acid and acetaldehyde. Glyoxal is also obtained as the main product from the oxidation ofd-tartaric acid.

Anodic Oxidation of Organics on Oxide Anodes
1998The electrochemical oxidation (or combustion) of organics with simultaneous oxygen evolution has been investigated using different oxide electrodes. A simplified mechanism for the electrochemical oxidation of organics is presented, according to which selective oxidation occurs with oxide anodes (MOx) for which the formation of higher oxides (e.g.: MOX ...

ECS Meeting Abstracts, 2023
Previously [1] we studied the anodic oxidation of symmetrical bisamides of type RCONH(CH2)nNHCOR (n = 2-4) under constant current electrolysis (CCE), in methanol. Those with 3 and 4 methylene groups as spacers undergo mostly mono- and dimethoxylation at the alpha-position to 'N' atom.

Hg0.70Cd0.30Te anodic oxidation
Journal of Vacuum Science and Technology, 1982It has been determined that anodic oxidation of (Hg,Cd)Te proceeds via a dissolution– precipitation mechanism. The initial film formation can be understood in terms of electrochemical parameters and, therefore, can be controlled in a rational manner.

Organocatalyzed Anodic Oxidation of Aldehydes
Journal of the American Chemical Society, 2012A method for the catalytic formation of electroauxiliaries and subsequent anodic oxidation has been developed. The process interfaces N-heterocyclic carbene-based organocatalysis with electro-organic synthesis to achieve direct oxidation of catalytically generated electroactive intermediates. We demonstrate the applicability of this method as a one-pot

Anodic oxidation of benzoquinone using diamond anode
Environmental Science and Pollution Research, 2014The anodic degradation of 1,4-benzoquinone (BQ), one of the most toxic xenobiotic, was investigated by electrochemical oxidation at boron-doped diamond anode. The electrolyses have been performed in a single-compartment flow cell in galvanostatic conditions. The influence of applied current (0.5-2 A), BQ concentration (1-2 g dm(-3)), temperature (20-45

Anodization current efficiency measurements were used to determine the oxygen content of sputtered tantalum films. Films consisting mainly of b.c.c. Ta had less than 5 at.% oxygen while 'normal' β-Ta contained 10–15 at.% oxygen. Films with a more negative temperature coefficient of resistance had a higher oxygen content.The field strength required to ...
