摘要:
为了应对内分泌干扰物对水生环境的危害问题，采用零价铁（ZVI）活化高铁酸盐［Fe（Ⅵ）］去除水中典型内分泌干扰物双酚AF（BPAF）。分别在纯水和实际水体中考察ZVI剂量、Fe（Ⅵ）初始浓度和初始pH对BPAF去除效果的影响。同时，通过三维荧光光谱技术表征实际水体中的有机物。结果表明，Fe（Ⅵ）/ZVI体系对纯水体系中BPAF的去除率高达90.56%，不同反应参数下BPAF的降解遵循假一级动力学模型。实际水体中含有芳环结构的类蛋白物质可能更易与Fe（Ⅵ）反应，但是体系对BPAF和溶解性有机物均有较好的去除效果，去除率分别为82.57%和60.2%。另外，Fe（Ⅵ）和ZVI二者存在协同效应，体系中可能产生以中间价态的铁［Fe（Ⅳ）/Fe（Ⅴ）］为主的活性物质，加速氧化BPAF。
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.
