Bisphenol F (BPF) is an organic compound used as a replacement for bisphenol A (BPA) in plastics. We investigated the rate at which BPF photodegrades under UV-C light. The fluence was determined with periodate chemical actinometry. We exposed test solutions of BPF to UV doses (fluence) of 370 mJ/cm2 to 2200 mJ/cm2 (1 h to 7 h) with a low pressure germicidal UV lamp. These samples were then analyzed by HPLC to determine the concentration of BPF remaining after UV photolysis. Results reveal that after exposure to 2200 mJ/cm2, only 22% BPF was removed from the solution, this indicates that BPF is difficult to degrade. We also examined whether the degradation of BPF can be enhanced with H2O2/UV advanced oxidation processes (AOPs). The results from this investigation indicate that BPF solutions reacted with UV/H2O2 revealed up to 41% degradation of BPF at a fluence of 370 mJ/cm2. We are currently examining the effects of varied concentrations of H2O2 on BPF degradation rates. In addition, we are currently determining possible breakdown products of UV and H2O2/UV destruction of BPF by LC-MS.
