Abstract
The reaction kinetics and transformation pathways between bisphenol F (BPF) and sodium hypochlorite were investigated at pH values ranging from 6.5 to 8.5 and with different initial concentration ratios. The reaction rate was pH- and free available chlorine (FAC)-dependent: the reaction rate at pH 8.5 was almost 10 times than that at pH 6.5. A total of 40 compounds were tentatively identified as chloro-substituted BPF and polyphenolic compounds by liquid chromatography quadrupole time-of-flight mass spectrometry operating in electrospray ionization mode (LC-ESI-Q-ToF), and 4 main byproducts were confirmed by 1H and 13C nuclear magnetic resonance (NMR). Toxicity tests indicated that the estrogenic effects of chloro-substituted BPF decrease as the chlorine substitution increase. On the contrary, increasing numbers of chlorines on the phenolic rings of BPF enhanced the nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ) activity. Tetra-chlorinated BPF had an approximately 6.9-fold higher activity than BPF.
