The degradation of pentoxifylline (PTX) using H2O2, UV, H2O2/UV, Fenton and photo- Fenton processes has been examined in aqueous solution. The influence of various amount of oxidation agent on H2O2, H2O2/UV, Fenton and photo-Fenton reactions were investigated. Initial PTX concentration in Fenton and photo-Fenton was considerated. The addition of inorganic ions (Cl-, NO3-, SO42- and CO32-) on the degradation efficiency of PTX were tested for H2O2/UV, Fenton and photo-Fenton rocesses. The results indicate that the photo-Fenton reaction is the most sufficient for PTX removal. The complete pharmaceutics decomposition is achieved after 5 min under optimized concentration of FeSO4·7H2O and H2O2. The degradation of PTX is inhibited in the presence of inorganic matter in H2O2/UV and Fenton reaction. In the photo-Fenton process addition of above compounds does not affect the reaction rate. Structures of nine products of photo-Fenton reaction have been proposed.
