For most standard tests, the working electrode is a bismuth or mercury film electrode (in a disk or planar strip configuration). The mercury film forms an amalgam with the analyte of interest, which upon oxidation results in a sharp peak, improving resolution between analytes. The mercury film is formed over a glassy carbon electrode. A mercury ...
Simple scheme of the apparatus for electro-oxidation process. The set-up for performing an electro-oxidation treatment consists of an electrochemical cell.An external electric potential difference (aka voltage) is applied to the electrodes, resulting in the formation of reactive species, namely hydroxyl radicals, in the proximity of the electrode surface.

Industrial Standards for Prebaked Carbon Anodes [4] [5] [6] Property Standard Range; Baked apparent density: ISO 12985-1: 1.53-1.64 gcm-3 Electrical resistance: ISO 11713: 55-62 μΩ for pressed anodes Compressive strength: ISO 18515: 40-48 MPa Young's modulus: RDC-144: 3.5-5.5 GPa Tensile strength: ISO 12986-1: 8-10 MPa for pressed anodes ...
Equatic’s process combines electrolysis with direct air capture to provide two valuable products, creating a dual-revenue stream. Its clean hydrogen production will help subsidize the cost of carbon removal, quickly bringing it down to less than $100 per tonne before 2030. The OSAs will be manufactured at a San Diego electroplating facility.
Most electrodes work over a limited range of conditions, such as pH or temperature, outside of this range the electrodes behavior becomes unpredictable. The advantage of a pseudo-reference electrode is that the resulting variation is factored into the system allowing researchers to accurately study systems over a wide range of conditions.
Capacitive deionization (CDI) is a technology to deionize water by applying an electrical potential difference over two electrodes, which are often made of porous carbon. [2] In other words, CDI is an electro-sorption method using a combination of a sorption media and an electrical field to separate ions and charged particles. [3]
A carbon-paste electrode (CPE) is made from a mixture of conducting graphite powder and a pasting liquid. [1] These electrodes are simple to make and offer an easily renewable surface for electron exchange. Carbon paste electrodes belong to a special group of heterogeneous carbon electrodes.
SOEC 60 cell stack. A solid oxide electrolyzer cell (SOEC) is a solid oxide fuel cell that runs in regenerative mode to achieve the electrolysis of water (and/or carbon dioxide) [1] by using a solid oxide, or ceramic, electrolyte to produce hydrogen gas [2] (and/or carbon monoxide) and oxygen.
