Abstract

Decomposition and complete degradation of two endocrine disrupters, namely 17β-estradiol (E₂) and bisphenol A (BPA) in aqueous medium by using ozone (O₃) only and O₃/UV advanced oxidation techniques (AOT) has been studied. The efficiency of the O₃ systems used were determined based on the initial conversion and complete degradation of the substrates. Within the limits of the O₃ dosages used, coupling of UV decreased the O₃ consumption by 22.5% in converting the same amount of E₂. Also the time to convert the same amount of E ₂ was considerably decreased. It was observed that there is no significant difference in O₃ amount consumed for complete conversion of BPA by O₃ and O₃/UV systems. However, when O ₃ dosage decreased the amount of BPA conversion exhibits significant differences between two processes. The intermediate products formed during the oxidation of E₂ were determined to be formed by oxidation of aromatic side of E₂ with O₃/^•OH radical.
