The performance of several catalysts (Fe (III), Fe (II) and TiO2) for the removal of phthalic anhydride by gliding arc plasma was studied, among which Fe (II) was the best catalyst (75 % of removal after 180 min). Indeed, the addition of Fe (II) into the reaction allows a better elimination of the organic matter through the production of additional .OH radicals. The oxidation of Persistent Organic Pollutants present in landfill leachate was studied by varying the loading of TiO2, and after 8h of treatment 51 % of removal was reached for 15 g L-1 of TiO2.
