Description: In this work, the solubility of C02 in aqueous blended systems of N-methyldiethanolamine (MDEA) and guanidinium trifluoromethanesulfonate (|gua]*[OTf]~) have been carried out. The solubilities were measured at temperature 303.2 K, 323.2 K and 333.2 K, over C02 partial pressure ranging from 500 to 3000 kPa. All data were reported as loading capacity (mol C02 /total mol) as a function of partial pressure of C02 at the corresponding temperature. It has been found that the aqueous [gua]*[OTf]- ionic liquid gave significantly higher solubility, up to 1.63 mol C02/total mol, as compared to other pure ionic liquids such as [bmim]*[BF4]-, [iemim]*[OTf)- and [emim]+[C2N3]- which recorded at 323.2K and 3000kPa. However, the addition of |gua]+[OTf]- ionic liquid to aqueous MDEA gave a slight decreased on solubility. Correlations of solubility as a function of partial pressure and temperature were obtained with deviation of ±0.957%.
