Method/Apparatus/Procedure:
The solubility was measured in a glass vessel which was filled with a calibrated volume of solvent. The solvent was degassed, and the vapor-liquid equilibrium was established. Equilibrium pressure was recorded by a pressure transducer. The gas was fed to the vessel until an arbitrary pressure ($P \le \pu{E5 Pa}$) was reached. The pressure was recorded again. The vessel was closed, and the magnetic stirrer was started to agitate the liquid. After the equilibrium pressure was reached the solubility was calculated, based on Henry's law.
In the paper the authors report solubility and diffusivity of $\ce{CO2}$ and $\ce{N2O}$ in water and aqueous alkanolamine solutions.
Source and Purity of Materials:
