- The degradation of pentoxifylline (PTX) using H2O2, UV, H2O2/UV, Fenton and photo-Fenton processes has been examined in aqueous solutions. The influence of oxidation agent and initial PTX concentration, on H2O2, H2O2/UV, Fenton and photo-Fenton reactions was investigated. The addition of inorganic ions (Cl–, NO3–, SO42– and CO32–) on the degradation efficiency of PTX was tested for H2O2/UV, Fenton and photo-Fenton processeses. 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,·7 H2O2 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 ten products of photo-Fenton reaction have been proposed.
