Photocatalytic destruction of fulvic acids by ozone and oxygen

We have studied destruction of river fulvic acids in water environment with ozone and oxygen. We have also determined advantages of catalytic and photocatalytic ozonization of their solutions compared with ozonization and O3/UV treatment. Photocatalytic ozonization secures the highest degree of destruction of fulvic acids (93% in terms of total organic carbon) at a shorter time and specific consumption of ozone compare with other methods of oxidation.
