The remediation of residual industrial water and soils contaminated with phenolic compounds using supercritical carbon dioxide extraction can be a potential and practical solution to this issue. For instance, SCF can eliminate the large volumes of waste solvent arising from soil-washing processes [1]. As part of the development of a remediation process of contaminated water and soils using supercritical fluids, the liquid densities of the binary system CO2 + m-cresol was measured at temperatures between (313.to 363) K and pressures up to 25 MPa.
