Abstract

In the present study, the removal of PAHs from industrial treatment sludge by using ultraviolet (UV) irridation and titanium dioxide (TiO2) was investigated. Twelve PAHs (Sigma(12) PAHs) were targeted and their levels in the sludge were studied. TiO2 was added at the ratio of 5% and 20% of the dry matter (DM) of the sludge. At 45 degrees C, 35% of the Sigma(12) PAHs were removed with only UV light. Higher PAH removal ratios were obtained employing TiO2 as a photocatalyst. At 45 degrees C, Sigma(12) PAH removal ratio was reached to 83% with using TiO2 at the ratio of 20%.
