Bisphenol A (BPA; 4‐[2‐(4‐hydroxyphenyl)propan‐2‐yl]phenol) is a substance typically used in the plastic industry. It is used in the production of epoxy resins, polycarbonate, or fire retardants or as a stabilizer and an antioxidant in numerous types of plastics. Bisphenol A is introduced into the environment via municipal and industrial wastewater. Because of its hydrophobic properties, BPA has the potential for sorption on activated sludge during the biological wastewater treatment processes. This study investigated the degradation of BPA by means of UV‐radiation and in the UV/H 2 O 2 process with the presence and absence of hydrocarbonate ions (HCO 3 − ) as hydroxyl radicals (OH • ) scavengers. The calculated value of quantum yield was equal to 0.18, and the value of BPA rate constant with hydroxyl radicals was equal to 3.3 × 10 9 M − 1 •s − 1 .
