The use of unmodified and chemically treated natural fibers for water remediation (removal of chemical residues/oil spills and organic wastewater from water) is a significant and low-cost strategy to reduce the contamination of aquifers with metal ions, as well as marine environments with oil spills and water bodies with organic dyes. Furthermore, synthetic fibers exhibit a superior performance owing to their tunable surface area and superhydrophobic/swelling properties. This review summarizes the most recent advances in natural fiber-based biosorbents and synthetic fiber mats since the efficient removal of toxic compounds depend on adequate incorporation of functional groups on the fiber surface for mutual electrostatic and diffusion of contaminants into the fibrils. The most relevant results in the removal of oil, trace metal ions, and organic dyes are presented and evaluated. The evaluation is done according to the strategies for chemical modification of raw materials by the reuse of plastics or conventional electrospinning techniques to support the hierarchical growth of more complex chemical structures.

用于水修复的天然和合成纤维基吸附剂

使用未经改性和化学处理的天然纤维进行水修复（去除水中的化学残留物/溢油和有机废水）是减少含水层被金属离子以及海洋环境污染的一项重要且低成本的战略。用有机染料处理漏油和水体。此外，合成纤维由于其可调节的表面积和超疏水/溶胀特性而表现出优异的性能。本综述总结了基于天然纤维的生物吸附剂和合成纤维垫的最新进展，因为有毒化合物的有效去除取决于在纤维表面充分结合官能团，以实现相互静电和污染物扩散到原纤维中。在去除油、痕量金属离子、和有机染料的介绍和评估。评估是根据原材料的化学改性策略进行的，通过再利用塑料或传统的静电纺丝技术来支持更复杂化学结构的分层增长。
