Soda lime canister used in anaesthetic machines to act as a carbon dioxide scrubber. Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats.
Other strong bases such as soda lime, sodium hydroxide, potassium hydroxide, and lithium hydroxide are able to remove carbon dioxide by chemically reacting with it. In particular, lithium hydroxide was used aboard spacecraft , such as in the Apollo program , to remove carbon dioxide from the atmosphere.
Pure lime is soluble in water containing carbonic acid, a natural, weak acid which is a solution of carbon dioxide in water and acid rain so it will slowly wash away, but this characteristic also produces autogenous or self-healing process where the dissolved lime can flow into cracks in the material and be redeposited, automatically repairing ...
Baralyme is a mixture of 80% calcium hydroxide and 20% barium hydroxide compounds [1] [2] [3] that is used as an alternative to soda lime to absorb the exhaled carbon dioxide in a closed circuit anesthetic system.
As the reaction between carbon dioxide and soda lime is exothermic, temperature sensors along the length of the scrubber can be used to measure the position of the reaction front and therefore the projected life of the scrubber. This is limited by measuring only along the line of sensors, it cannot detect bypasses or channelling. [28] [29]
A simple whole plant respirometer designed to measure oxygen uptake or CO 2 release consists of a sealed container with the living specimen together with a substance to absorb the carbon dioxide given off during respiration, such as soda lime pellets or cotton wads soaked with potassium hydroxide. The oxygen uptake is detected by manometry. [5]
Unlike club soda or seltzer, sparkling waters often come in a range of flavors, made with natural or artificial flavorings (like key lime, coconut, or mango), fruit juices (such as yuzu, pineapple ...
The Solvay process or ammonia–soda process is the major industrial ... Instead of treating the remaining solution with lime, carbon dioxide and ammonia are pumped ...
