Solubility of carbon dioxide in aqueous solutions containing sodium acetate or ammonium acetate at temperatures from 313 to 433 K and pressures up to 10 MPa

The solubility of carbon dioxide was measured in aqueous solutions containing the single salts sodium acetate and ammonium acetate corresponding to salt molalities in the liquid phase of about 4 mol/kg and 6 mol/kg in the temperature range from 313 K to 433 K at total pressures up to 10 MPa. Pitzerʹs semiempirical model for the excess Gibbs energy of aqueous electrolyte solutions is used to correlate the new data. Experimental results are reported and compared to correlations.
