how the earlier mentioned substance can be used in air purification?
Lithium hydroxide absorbs carbon dioxide from the air by forming lithium carbonate and releases oxygen.
Lithium
Lithium hydroxide absorbs carbon dioxide from the air by forming lithium carbonate, and is preferred over other alkaline hydroxides for its low weight.

Lithium peroxide (LiO) in presence of moisture not only reacts with carbon dioxide to form lithium carbonate, but also releases oxygen.
where does most of the world's lithium come from South America what are the uses of it? It has several industrial applications, including heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminium production, lithium batteries, and lithium-ion batteries. in which living beings this substance can be found? Marine organisms and terrestrial organisms. how this substance can be produce artificially? It is produced through electrolysis from a mixture of fused 55% lithium chloride and 45% potassium chloride at about 450 °C. what do you mean by the term you just mentioned? It is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. who introduced this term? Michael Faraday what is the process of this technique? The key process is the interchange of atoms and ions by the removal or addition of electrons due to the applied current. can you mention any related techniques of it? UNANSWERABLE how this technique or process can be use in industries? UNANSWERABLE

Lithium [SEP] Air purification
Lithium chloride and lithium bromide are hygroscopic and are used as desiccants for gas streams. Lithium hydroxide and lithium peroxide are the salts most used in confined areas, such as aboard spacecraft and submarines, for carbon dioxide removal and air purification. Lithium hydroxide absorbs carbon dioxide from the air by forming lithium carbonate, and is preferred over other alkaline hydroxides for its low weight. Lithium peroxide (LiO) in presence of moisture not only reacts with carbon dioxide to form lithium carbonate, but also releases oxygen. The reaction is as follows: Some of the aforementioned compounds, as well as lithium perchlorate, are used in oxygen candles that supply submarines with oxygen.
