| Resumo | |
Confined water in aqueous solutions of imidazolium-based ionic liquids (ILs) associated with acetate and imidazolate anions react reversibly with CO2 to yield bicarbonate. Three types of CO2 sorption in these ``IL aqueous solutions{''} were observed: physical, CO2-imidazolium adduct generation, and bicarbonate formation (up to 1.9mol(bicarbonate) mol(-1) of IL), resulting in a 10:1 (molar ratio) total absorption of CO2 relative to imidazolate anions in the presence of water 1:1000 (IL/water). These sorption values are higher than the classical alkanol amines or even alkaline aqueous solutions under similar experimental conditions. (AU) | |
