Specific organic pollutants (SOPs) such as phenolic compounds, PAHs, organic pesticides, and organic herbicides cause health and environmental problems due to their excessive toxic properties and poor biodegradability. Low-cost biosorbents are considered as a promising alternative for conventional adsorbents to remove SOPs from water. These materials have several advantages such as high sorption capacities, good modifiability and recoverability, insensitivity to toxic substances, simple operation in the treatment processes. However, previous reports on various types of biosorbents for removing SOPs are still moderately fragmented. Hence, this paper provides a comprehensive review on using typical low-cost biosorbents obtained from lignocellulose and chitin/chitosan for SOPs adsorption. Especially, their characteristics, biosorption mechanism together with utilization for eliminating SOPs are presented and discussed. The paper also gives a critical view regarding future applications of low-cost biosorbents in SOPs-contaminated water treatment.
特定有机污染物（SOPs）如酚类化合物、多环芳烃、有机农药和有机除草剂，由于其过高的毒性和较差的生物降解性，会引发健康和环境问题。低成本生物吸附剂被认为是传统吸附剂的一种很有前途的替代品，可用于从水中去除 SOPs。这些材料具有高吸附容量、良好的可修饰性和可回收性、对有毒物质不敏感、在处理过程中操作简单等优点。然而，之前关于各种类型的生物吸附剂去除 SOPs 的报告仍然比较零散。因此，本文综述了利用木质纤维素和甲壳素/壳聚糖获得的典型低成本生物吸附剂去除 SOPs 的研究进展。特别介绍并讨论了它们的特性、生物吸附机制以及用于去除 SOPs 的应用。本文还对低成本生物吸附剂在 SOPs 污染水处理中的未来应用进行了批判性的评价。
