Abstract
The photocatalytic degradation of three hydroxylated bicyclic aromatic compounds (2,2'-dihydroxybiphenyl, 4,4'-dihydroxybiphenyl and 4-hydro xybiphenyl) in contact with TiO2, in aqueous unbuffered solution was a chieved. The main intermediate, in all cases, was 1,2,4-trihydroxybenz ene. The photoxidation of this intermediate led to identified compound s: maleic acid, muconic acid and butadiene, resulting from the aromati c ring opening. A complete mineralization scheme for hydroxylated bicy clic aromatic compounds can be proposed.
