Electrolytic Solution - an overview | ScienceDirect Topics

In an electrolytic cell, the control of pH values is possible only by changing the composition of the electrolyte solution by means of acidic or basic reagents. However, the reactions in Eqs [4.5]–[4.7] result in a localised pH increase at the hode/electrolyte interface: Zhang et al. (1998) showed that this is a function of the current

involved electrowinning of a calcium-tin alloy followed by electrorefining to produce calcium metal. In the electrowinning cell, CaCI2 was fed to a KCI2-CaCI2 electrolyte. The calcium was electrowon at 6500 C into the pure molten tin hode until contained 7.5 wt pct Ca. Current efficiency for electrowinning averaged over 90 pct.

Industry – Innovation Gaps – Analysis - IEA

Innovation efforts are currently under way to avoid CO 2 emissions in industry, such as through low-carbon, hydrogen-based production of steel and chemicals; using alternative, lower-carbon binding materials in cement; and employing inert anodes for primary aluminium production. Other efforts focus on CCUS, particularly in the iron and steel, chemical and cement subsectors.

Status of Chlorate Regulations & Impact on Water Treatment

Saturated brine enters the electrolytic cell. Electrical current is passed through the electrolytic cell producing oxidant. Hydrogen gas produced during the electrolysis process is vented outside. Oxidant solution leaves the electrolytic cell and is stored in the oxidant tank. Oxidant solution is dosed into the treatment process by a metering pump.
