of polysulphides in solution in anhydrous alcohol, then reacting the Na2S obtd. with a polysulphide (mixt) giving a mixt. which is richer in sodium, then separating the sodium by electrolysis in a cell using a beta-Al2O3 electrolyte working at 250-300 degrees C, where the polysulphide ...
PROCESS FOR THE RECOVERY OF MERCURY FROM THE BRINE FILTER SLUDGE OBTAINED IN THE ELECTROLYSIS OF ALKALI METAL CHLORIDES BY THE AMALGAM PROCESS Process for the recovery of mercury from the brine filter sludge of alkali-chlorine cells. The brine filter sludge is treated with solutions containing ...
The results obtained reveal that corrosion rate of the graphite anodes during electrolysis of brine takes place 1.(1) due to the neucleophilic attack of water, and2.(2) via the formation of a chloride-graphite compound having the chemical formula: The compound was isolated and identified. It...
electrolysisbrineSmall on-site electrochemical generators producing a "mixture of oxidants" (e.g.ozone, hypochlorous acid, and possibly other highly energetic intermediate species) from brine is a technology that holds great promise for the small utility. The prese...

A method for inhibiting the formation of Mercury and \\/ or Butter to break the already formed during the Electrolysis of brine of alkali metal. It consists of the following steps: 1) in a Brine Electrolysis of electrolyzer. 2) separation of a mixture rich in metal Alkaline electrolyzer. 3...
A method for inhibiting the formation of Mercury and Butter - or to break the already formed during the Electrolysis of brine of alkali metal.The present invention relates to a method of inhibiting the formation of and/or breaking of preformed mercury butter in chlor-alkali cells. The method ...
Membraneless electrolyzers offer a promising approach to convert environmentally harmful reject brine waste streams generated from desalination into valuable products, such as mineral carbonates, by using electrochemical reactions to split the brine into acidic and alkaline streams. However, membraneless ...
Abiotic processes take place when hydrogen interacts with non-living objects such as rock minerals, oil, gas, and brine. Aqueous reactions and mineral dissolution/precipitation reactions are examples of abiotic processes [21,24]. One of the important factors that must be taken into account during ...
