Accumulation of polycyclic aromatic hydrocarbons (PAH) poses significant dangers to the environment and human health. The advancement of technology for cleaning up PAH-contaminated environments is receiving more attention. Adsorption is the preferred and most favorable approach for cleaning up sediments polluted with PAH. Due to their affordability and environmental friendliness, carbonaceous adsorbents (CAs) have been regarded as promising for adsorbing PAH. However, adsorbent qualities, environmental features, and factors may all significantly impact how well CAs remove PAH. According to growing data, CAs, most of which come from laboratory tests, may be utilized to decontaminate PAH in aquatic setups. However, their full potential has not yet been established, especially concerning field applications. This review aims to concisely summarize recent developments in CA, PAH stabilization processes, and essential field application-controlling variables. This review analysis emphasizes activated carbon, biochar, Graphene, carbon nanotubes, and carbon-nanomaterials composite since these CAs are most often utilized as adsorbents for PAH in aquatic systems.
多环芳烃(PAH)的积累对环境和人类健康构成重大威胁。清理受PAH污染环境的技术进展正受到越来越多的关注。吸附是清理受PAH污染沉积物的首选且最有利的方法。由于其价格低廉且环保,碳质吸附剂(CAs)被认为在吸附PAH方面很有前景。然而,吸附剂质量、环境特征和因素都可能对CAs去除PAH的效果产生重大影响。根据越来越多的数据,CAs(其中大部分来自实验室测试)可用于净化水生环境中的PAH。然而,它们的全部潜力尚未确定,特别是在现场应用方面。本综述旨在简要总结CAs、PAH稳定化过程以及重要的现场应用控制变量的最新进展。本综述分析重点关注活性炭、生物炭、石墨烯、碳纳米管和碳纳米材料复合材料,因为这些CAs在水生系统中最常被用作PAH的吸附剂。
