Abstract：
Organophosphate esters (OPEs) are widely used commercial additives, but their environmental persistence and toxicity raise serious concerns necessitating associated remediation strategies. Although there are various existing technologies for OPE removal, comprehensive screening for them is urgently needed to guide further research. This review provides a comprehensive overview of the techniques used to remove OPEs from soil and water, including their related influencing factors, removal mechanisms/degradation pathways, and practical applications. Based on an analysis of the latest literature, we concluded that (1) methods used to decontaminate OPEs include adsorption, hydrolysis, photolysis, advanced oxidation processes (AOPs), activated sludge processes, and microbial degradation; (2) factors such as the quantity/characteristics of the catalysts/additives, pH value, inorganic ion concentration, and natural organic matter (NOM) affect OPE removal; (3) primary degradation mechanisms involve oxidation induced by reactive oxygen species (ROS) (including •OH and SO4•-) and degradation pathways include hydrolysis, hydroxylation, oxidation, dechlorination, and dealkylation; (5) interference from the pH value, inorganic ion and the presence of NOM may limit complete mineralization during the treatment, impacting practical application of OPE removal techniques. This review provides guidance on existing and potential OPE removal methods, providing a theoretical basis and innovative ideas for developing more efficient and environmentally friendly techniques to treat OPEs in soil and water.
摘要：
有机磷酸酯（OPEs）是广泛使用的商业添加剂，但是它们的环境持久性和毒性引起了人们的严重关注，需要相关的修复策略。尽管有各种现有的OPE去除技术，迫切需要对它们进行全面筛查，以指导进一步的研究。这篇综述全面概述了用于从土壤和水中去除OPEs的技术，包括它们的相关影响因素，去除机制/降解途径，和实际应用。在对最新文献进行分析的基础上，我们得出的结论是(1)用于净化OPEs的方法包括吸附，水解，光解，高级氧化工艺(AOPs)，活性污泥法,和微生物降解；（2）催化剂/添加剂的数量/特性等因素，pH值,无机离子浓度，和天然有机物（NOM）影响OPE的去除；（3）主要降解机制涉及活性氧（ROS）（包括•OH和SO4•-）诱导的氧化，降解途径包括水解，羟基化,氧化，脱氯,脱烷基化；（5）pH值的干扰，无机离子和NOM的存在可能会限制处理过程中的完全矿化，影响OPE去除技术的实际应用。这篇综述为现有和潜在的OPE去除方法提供了指导，为开发更有效，更环保的技术来处理土壤和水中的OPEs提供了理论基础和创新思路。
