Removal of Bisphenol A from Water by Ozone

Abstract:

This study investigates the degradation of bisphenol A (BPA). The degradation affecting factors including solution ozone dosage, initial concentration, pH, temperature and ultraviolet. The results indicated that when the ozone contents changes, the BPAs degradation rate changes as well. The higher ozone concentration contribute to the faster degradation; With the increase of initial concentration of BPA, the removal rate of it decrease on the contrary, while with the initial concentration increases, the quality of unit ozone degradation of BPA is ascenting and then tend to a constant; The remove rate of BPA is improving when the pH value vary from 4.86~10.34. The effect of BPAs ozonation in higher temperatures is better than it is in lower temperature; Ultraviolet radiation is also favorable for the removal of BPA as it can shorten the reaction time as well as reduce the amount of ozone.
