According to recent research from Turin, Italy, "This work was aimed at evaluating the feasibility of a remediation treatment performed by means of a supercritical carbon dioxide extraction on a sandy soil recently contaminated by light polycyclic aromatic hydrocarbons. The soil utilized in this study was artificially contaminated by naphthalene and anthracene."
"The artificial contamination process was intended to simulate a recent accidental spillage of hydrocarbon fuels. Several extractions, aimed at singling out the operating parameters (pressure, temperature, supercritical fluid mass flow rate) that are able to obtain the residual required concentration (50 mg/kg …
