Degradation of bisphenol A in wastewater by advanced oxidation processes

Abstract

Bisphenol A (BPA) is one of the important emerging organic micropollutants frequently detected in various aquatic environments, including wastewater. Due to its high chemical stability, pronounced endocrine-disrupting effects, and limited removal efficiency by conventional treatment processes, BPA represents a challenge for modern water treatment technologies. In this study, the degradation of BPA in wastewater was investigated using a UV/H2O2 process. BPA removal >90% was achieved at a higher initial hydrogen peroxide concentration and a UV irradiation dose of 1000 mJ/cm2. In parallel, changes in aromatic structure indicators, the degree of mineralization, and total organic load were monitored as indicators of organic matter transformation.
