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.
