As emerging contaminants, PAEs (Phthalic Acid Esters or Phthalate Esters) have been extensively utilized in industrial production to soften the rigid plastics (plasticizers), and their related products are widely distributed in our daily life. The PAEs can readily transfer from the products to the surrounding environment due to not being chemically bound to the products. In this study, we analyzed the PAEs' properties, usage, and consumption in the world, as well as toxicity to human beings. As endocrine-disrupting chemicals (EDCs), PAEs can disturb the normal hormones reactions, resulting in developmental and reproductive problems. Thus, we have to concern the removal strategies of PAEs. We summarized two novel approaches, including biochars and persulfate (PS) oxidation for effectively removing PAEs in the literature. Their characteristics, removal mechanisms, and the main impact factors on the removal of PAEs were highlighted. Moreover, transition metal-activated PS showed good performance on PAEs degradation. Furthermore, the synergy of biochars and transition metals-PS can overcome the disadvantages of a single approach, and show better performance on the removal of PAEs. Finally, we put forward vital strategies to update two approaches (including the combined) for enhancing the removal of PAEs. It is expected that the researchers or scientists can get a hint on effectively remediating PAEs-contaminated sites via the biochars' sorption/transition metals-PS or the combined two from this review paper.
作为新兴污染物，邻苯二甲酸酯（Phthalic Acid Esters 或 Phthalate Esters）被广泛应用于工业生产中，以软化刚性塑料（增塑剂），其相关产品广泛分布在我们的日常生活中。由于邻苯二甲酸酯没有与产品发生化学反应，因此很容易从产品转移到周围环境中。在本研究中，我们分析了邻苯二甲酸酯在世界范围内的性质、用途和消耗情况，以及对人类的毒性。作为内分泌干扰化学物质（EDCs），邻苯二甲酸酯会干扰正常的激素反应，导致发育和生殖问题。因此，我们必须关注邻苯二甲酸酯的去除策略。我们在文献中总结了两种去除邻苯二甲酸酯的新方法，包括生物炭和过硫酸盐（PS）氧化。强调了它们的特性、去除机制以及对去除邻苯二甲酸酯的主要影响因素。此外，过渡金属激活的过硫酸盐在去除邻苯二甲酸酯方面表现出良好的性能。此外，生物炭和过渡金属-过硫酸盐的协同作用可以克服单一方法的缺点，在去除邻苯二甲酸酯方面表现出更好的性能。最后，我们提出了重要的策略来更新两种方法（包括联合方法），以增强去除邻苯二甲酸酯的效果。希望本综述能为研究人员或科学家提供通过生物炭吸附/过渡金属-过硫酸盐或联合两种方法有效修复邻苯二甲酸酯污染场地的启示。
