Solubility was determined in the pressure range from 8 to 20 MPa and in the temperature range from 308 to 318 K. CO2 solubility in citrate buffer solutions at pH = 3.8 and pH = 6.2 was slightly lower than CO2 solubility in pure water. A Chrastil-type equation according to Fornari’s approach was used to fit CO2 solubility data in pure water and model solutions. A new term was introduced in this equation to account for the decrease in solubility of CO2 in the presence of sugar in the liquid media.
