“…Results show that none of the models were able to correctly describe the solubility data measured for norfloxacin. Similar results were previously reported for the solubility of cholesterol in scCO 2 [32] and they were justified by the different density dependences observed for each isotherm that do not permit that the same set of parameters is used to accurately describe the entire set of data. Correlation was not improved Table 4 Parameters from Sparks equation (Eqs.…”
