Lubricant oils undergo degradation increasing polycyclic aromatic hydrocarbons (PAHs) concentration In this work, PAHs adsorption onto activated carbon, powder silica, and powder chitosan surfaces was estimated, with their concentrations in organic solvents (ethanol, 2-propanol, 1-butanol, and terc-butanol) monitored by UV-visible absorption Equilibrium concentration was attained after 72 h and the isotherms presented characteristic of multilayer formation The greater surface density was determined for the chitosan, but the system containing activated carbon and 1-butanol presented better efficiency for PAHs removal Results indicated that the adsorption evaluated in this work can be a potential stage in the waste lubricant oils global recovery process
