- Abstract:
- Zero-valent iron (ZVI) activated ferrate [Fe(Ⅵ)] was employed for the removal of bisphenolAF (BPAF), a typical endocrine disruptor, from water, so as to address the impact of endocrine disruptors on the aquatic environment. The study investigated the impact of ZVI dosage, initial Fe(Ⅵ） concentration, and initial pH on the removal efficiency of BPAF in both pure water and actual water systems. Concurrently, the organic matter present in the actual water body was characterized using three-dimensional fluorescence spectroscopy. The removal rate of BPAF in the pure water system by the Fe(Ⅵ）/ZVI system was as high as 90.56%. The degradation of BPAF followed the pseudo-first-order kinetic model under different reaction parameters. In actual water, protein-like substances containing aromatic ring structures were more likely to react with Fe(Ⅵ). However, the system effectively removed BPAF and dissolved organic matter, with removal rates of 82.57% and 60.2%, respectively. Furthermore, there existed a synergistic effect between Fe(Ⅵ) and ZVI, leading to the production of active substances primarilycomposed of intermediate valent iron [Fe(Ⅳ)/Fe(Ⅴ)] in the system. These substances served to expedite the oxidation of BPAF.
