Activity of TiO۲ Nanomaterial for Photocatalytic Ozonation Degradation of Acetaminophen

Acetaminophen is one the most common medicines found in cabinets of houses which is used as a painkiller. Therefore acetaminophen is usually found in household wastewater and sewage of pharmaceutical factories and as a result is found in surface water. Acetaminophen in wastewater causes pollution, so its destruction is important. In the present study acetaminophen destruction with photocatalyst ozonation and in presence of titanium dioxide and under the effect of operating conditions was investigated. The results of degradation efficiency of acetaminophen in a batch system by various advanced oxidation processes revealed the order of TiO۲/UV/O۳>TiO۲/O۳>UV/O۳>O۳>UV/TiO۲. All processes followed pseudo-first order kinetics. The influence of operational parameters such as initial pH, initial concentration of acetaminophen, ozone and catalyst dosage on the TiO۲/UV/O۳ process, which was the most significant method was investigated. The ozone dosage was found to have the noticeable impact on the process, however initial pH and TiO۲ dosage were less effective
