Rather, the key to developing a CO2-scrubbing textile is carbonic anhydrase, or CA, a ubiquitous enzyme that’s central to maintaining acid-base homeostasis. CA is a neat little enzyme that coordinates a zinc ion in its active site and efficiently catalyzes the addition of water to carbon ...
of CO2 contained in air and water circulating through tectonic fractures, thermodiffusion of various gases having different molecular weights and under varying degrees of temperature and pressure, and variations in CO2 concentration due to external seasonal variations in temperature and protective snow ...
English: Dissolved CO2 in water can influence the acidity of a solution, leading to changes in the pH level. When CO2 dissolves in water, it forms carbonic acid (H2CO3), which can further dissociate into bicarbonate ions (HCO3-) and hydrogenions (H+). This process creates a weakly acidi...
and dissolves into water to form carbonic acid which reacts with part of metal salts to form water-soluble salts, resulting in the removal rate of K, Na and Ca up to above 50%, and part removal of calcite and dolomite. Also, the proposed process shows higher deashing efficiency and ...
The reaction mechanism is that the reaction rate is determined mainly by the solvation of C3AH6 in the initial stage of the reaction and subsequently by the ionization of carbonic acid in the late reaction stage. It is feasible to recover the alumina from C3AH6 by using CO2 as the reagent...

Plateau uplift may alter climate by increasing chemical weathering of rocks, thereby reducing atmospheric carbon dioxide concentrations. Carbon dioxide combines with rainwater and ground water to form carbonic acid, which reacts with silicate minerals in rocks during weathering. The resulting bicarbonate io...
