Abstract

The decomposition of bisphenol A (BPA) was investigated under various conditions including ultrasound (US) irradiation, ultraviolet (UV) irradiation, and the combination of both (US/UV). The effects of the operational parameters, such as initial BPA concentration, initial anion concentration (chloride and sulphate ions) and pH, were studied. Analyses were performed by high-performance liquid chromatography. BPA initial concentration of 5 mg/L, pH of 3, and irradiation time of 50 min were the optimum conditions for degradation of BPA by US/UV system. Besides, the optimized parameters were also tested for the treatment of natural water containing BPA. The maximum removal of BPA (94.5%) was observed in US/UV system at pH 3 after 50 min. Adding anions, such as chloride and sulphate, decreased the removal efficiency of US/UV system. It was found that chloride was the most powerful inhibitor. As a result, the efficiency of US/UV system in deionized water was higher than in natural water. Kinetic modelling applied for the obtained results showed that the degradation of BPA by US/UV followed the first-order model.
