多酚类化合物是一类广泛存在于自然界中的天然生物活性物质,毒性小、价格低、来源广等特点使其成为处理水中典型污染物的常用螯合剂、还原剂与封端剂等。目前,多酚通过偶联常见过渡金属离子以及过氧化物广泛应用于高级氧化工艺(AOPs),但多酚类物质在水污染治理过程中的化学机制仍缺乏系统性总结。本文总结了含多酚类化合物的均相与非均相体系构成以及多酚在体系中所展现的促氧化、抗氧化和螯合-还原作用,并从自由基和非自由基角度阐明了多酚类物质在不同体系下产生的主要活性物种以及对应的水体污染物去除机制。强调了多酚作为天然氧化还原介体在构建复杂催化体系过程中起到的氧化还原双重作用,描述了光、热、电、超声波、等离子体等外部能量对上述体系反应机制和污染物降解效果的影响。最后,对多酚类化合物在水处理领域的发展方向做出展望。

Polyphenolic compounds are a class of naturally occurring bioactive substances widely found in environment. Their characteristics, such as low toxicity, low cost, and broad availability, make them become to be widely used chelating agents, reducing agents and capping agents for treating typical pollutants in water. Currently, polyphenols are extensively used in advanced oxidation processes (AOPs) through the coupling of common transition metal ions and peroxides. However, the chemical mechanisms of polyphenolic substances in water pollution remediation still lack systematic conclusions. This study reviews and summarizes the compositions of homogeneous and heterogeneous systems containing polyphenolic compounds, as well as the pro-oxidant, antioxidant, and chelating-reduction effects exhibited by polyphenols within these systems. It explains the main active species generated by polyphenolic substances under different systems from both radical and non-radical perspectives, along with the corresponding mechanisms for the removal of water pollutants. The dual role of polyphenols as natural redox mediators (RMs) in constructing complex catalytic systems is emphasized, and the effects of external energies such as light, heat, electricity, ultrasound, and plasma on the reaction mechanisms and pollutant degradation effectiveness in these systems are described. Finally, the article looks ahead to the future development directions of polyphenolic compounds in the field of water treatment.
