Today, advanced oxidation processes (AOPs) is considered as a key and effective method for environment preservation from pollutions. In this study , advanced photochemical oxidation processes using O3/H2O2 and O3/H2O2/UV systems were investigated batch photolytic reactor in lab-scale for the degradation of bisphenol A (BPA). In ozone generator source, air, as of the initial instrument feed, changes to ozone after electrical action and reaction. The UV irradiation source was a medium-pressure mercury lamp 300 W that was immerse in the wastewater solution with in 1.5 liter volume reactor. The reaction was influenced by the pH, the input concentration of H2O2, the input concentration of BPA, ozone dosage, chemical oxidation demand (COD) and UV irradiation time. Results showed that at initial bisphenol A concentration of 100 mg/l will completely degrade after 60 minutes by using O3/H2O2 in the pH range from 9.8 to 10 and by adding UV, it will happen in less than 36 minutes in the pH range of 3 to 10. The O3/H2O2/UV process reduced COD to 75 percents.

The effect of change of solvent on the positions and intensities of absorption bands of some aromatic amines between 200 and 400 nm has been examined. In particular, the behavior of the band at 280 nm has been studied.In hydroxylic solvents, this band is displaced towards shorter wavelengths, and the dipole moment in the excited state of the molecule is smaller than in the ground state. The opposite effects are found when nonhydroxylic solvents are used.The results show how the molecular structure is altered by charge transfer effects and can explain how different solvents affect photochemical oxidation processes.
