Prior to this step, CO 2 density for all experimental state parameters was calculated using the Span and Wagner EoS. Given that a sharp increase in solubility can occur during the transition from the subcritical to the supercritical state of CO 2 , 18 the data cleaning procedure was applied exclusively to measurements conducted in the supercritical region. Solubility values were averaged over three or more data points as a function of CO 2 density. A relative deviation of 10% between the approximated solubility value and the experimental data was considered acceptable. Data points exceeding this deviation threshold were classified as outliers and subsequently excluded from the purified dataset.
