METHOD FOR DEGRADING POLYCYCLIC AROMATIC HYDROCARBONS BY USING AN IMMOBILIZED HEMOPROTEIN

摘要

The invention relates to a method for reducing the content of polycyclic aromatic hydrocarbons (PAH) of a liquid medium, said PAH's optionally containing, in their cyclic structure, one or more heteroatoms selected among N, O and S, comprising: (a) placing the liquid medium in contact with at least one appropriate oxidizing agent in the presence of at least one hemoprotein selected among hemoglobins and myoglobins, immobilized on or in finely divided solid mineral particles having an average size determined by laser granulometry ranging from 5 nm to 1 mm, preferably from 10 nm to 100 µm, in reaction conditions that permit the oxidation of polycyclic aromatic hydrocarbons optionally sulfurated and/or nitrogenated and/or oxidized by the oxidizing agent, and; (b) the separation of the immobilized hemoprotein from the liquid medium.
