abstract: The densities of aqueous solutions of sodium glycinate (SG) were measured for a range of concentrations (1, 5, 10, 15, 20, and 30) % wt and at a temperature range (298.15 to 353.15) K. The solubility of CO2 in aqueous solution of sodium glycinate was measured for the same concentration range and at two temperatures (298.15 and 313.15) K, over CO2 partial pressure ranging from (100 to 2500) kPa. The densities of aqueous solutions of sodium glycinate after the absorption were also measured at the same conditions of the solubility measurements. It was found that density of aqueous solutions of sodium glycinate increases as the molar concentration increases and decreases with an increase in temperature. The solubilities of CO2 are reported as loading capacity (mol CO2/mol SG) as a function of partial pressure of CO2 at the corresponding temperature. It was found that CO2 solubility increases with increase in CO2 partial pressure. It was also found that solubility of sodium glycinate solution decreases with increasing sodium glycinate concentration and temperature. The densities of aqueous sodium glycinate after absorption gave a higher value than that before absorption and increase with increasing pressure. © 2009 American Chemical Society.
