The climate change assumes the warming of the climate systems due to increase of global average temperature to the observed increase of the greenhouse gas (GHG) concentration in the atmosphere. Carbon dioxide (CO2) is considered the most important GHG. The processes of CO2 capture are gaining a great attention on the scientific community as an alternative for decreasing CO2 emission and reducing its concentration in ambient air. In this study, we report a new deep eutectic solvents (DESs) made of monoethanolamine hydrochloride-diethylenetriamine exhibits a great candidate for CO2 capture. We developed solubility and physical properties studies at different pressures and temperatures, and regression model was well in agreement with the calculated αCO2 values with R-square: 0.976. The strong properties of DESs in CO2 capture make them as a suitable solvent for absorption CO2 to replace the conventional amine based scrubbing technology and are worth for further exploration.
