In the present study the mechanism of photocatalytic degradation of furfural in
wastewater was studied. The impregnation method was used to immobilize the
TiO2 nano particles on a glass support material. The performance of this coated
glass plate was tested into a photocatalytic reactor. The intermediate products that
produced in during of reaction have been analyzed by HPLC and HPLC-MASS.
Concerning the degradation mechanism of furfural, there are three steps generally expected, including aldehyde group oxidation, photo-oxidation of aromatic ring
and cleavage of ring. The intermediates of photo-oxidation of furfural were
maleic and 2, 3-Dihydroxy-succinic (tartaric), acids
