Absorption mechanism and kinetics of NO by Fe(II) based ethylene glycol (EG)-choline chloride (ChCl) deep eutectic solvents

Breaking new grounds: metal salts based-deep eutectic solvents and their applications- a comprehensive review

“…Dou et al 150 reported a series of Fe( ii ) EG–ChCl DESs as denitrification sorbents to trap NO from simulated flue gases. Fe( ii ) EG–ChCl DESs established efficient NO absorption activity and zero secondary pollution.…”

Ionic liquids and deep eutectic solvents for NH3 absorption and separation: a review

“…DESs often enjoy similar solvent properties with traditional ILs and low cost, degradability, simple preparation procedure, reliability in purity, and wide liquid range. 116–119 Since Abbott et al 120 first discovered DESs of ChCl/urea mixtures with novel solvent properties, DESs with their outstanding performances are extensively reported as a new medium to capture polluting gases, including acidic gases (SO 2 , 121–123 CO 2 , 124–126 H 2 S, 127–129 NO x 130–133 ) and alkaline gas (NH 3 ) by using their relatively low volatility to avoid solvent evaporation. Thus, the second solvent pollution and energy consumption can be substantially reduced during gas absorption and regeneration of absorbents.…”

Study on Mechanism and Thermodynamics of NO Absorption by Acetylcholine‐chloride Type Deep Eutectic Solvents

“…Because of its simple synthesis, convenient application, and environmental friendliness, many scholars have developed DESs to investigate the absorption of a series of gases, such as SO 2 , [15,16] CO 2 , [17–19] NH 3 , [20,21] and NO [22–24] …”

“…[11][12][13][14] Because of its simple synthesis, convenient application, and environmental friendliness, many scholars have developed DESs to investigate the absorption of a series of gases, such as SO 2 , [15,16] CO 2 , [17][18][19] NH 3 , [20,21] and NO. [22][23][24] Ionic liquid and DESs has good absorption and cycling properties, strong selectivity and high desorption rate for SO 2 and NH 3 and other gases. So scholars around the world will use them in industrial applications.…”
