Polycyclic aromatic hydrocarbons (PAHs) and phenolic compounds had been widely recognized as priority organic pollutants in wastewater with toxic effects on both plants and animals. Thus, the remediation of these pollutants has been an active area of research in the field of environmental science and engineering. This review highlighted the advantage of adsorption technology in the removal of PAHs and phenols in wastewater. The literature presented on the applications of various porous carbon materials such as biochar, activated carbon (AC), carbon nanotubes (CNTs), and graphene as potential adsorbents for these pollutants has been critically reviewed and analyzed. Under similar conditions, the use of porous polymers such as Chitosan and molecularly imprinted polymers (MIPs) have been well presented. The high adsorption capacities of advanced porous materials such as mesoporous silica and metal-organic frameworks have been considered and evaluated. The preference of these materials, higher adsorption efficiencies, mechanism of adsorptions, and possible challenges have been discussed. Recommendations have been proposed for commercialization, pilot, and industrial-scale applications of the studied adsorbents towards persistent organic pollutants (POPs) removal from wastewater.

用于去除废水中多环芳烃和酚的高多孔吸附材料的概述和评价

多环芳烃(PAHs)和酚类化合物已被广泛认为是废水中的优先有机污染物,对植物和动物都有毒性。因此,这些污染物的修复一直是环境科学与工程领域的一个活跃研究领域。这篇综述强调了吸附技术在去除废水中的多环芳烃和苯酚方面的优势。对各种多孔碳材料如生物炭、活性炭 (AC)、碳纳米管 (CNT) 和石墨烯作为这些污染物的潜在吸附剂的应用的文献进行了批判性审查和分析。在类似条件下,多孔聚合物如壳聚糖和分子印迹聚合物 (MIP) 的使用已得到很好的介绍。已经考虑和评估了高级多孔材料(如介孔二氧化硅和金属有机骨架)的高吸附能力。已经讨论了这些材料的偏好、更高的吸附效率、吸附机制和可能的挑战。已经提出了将所研究的吸附剂用于去除废水中的持久性有机污染物 (POPs) 的商业化、试点和工业规模应用的建议。
