Advances in electrospun materials for the adsorption and separation of environmental pollutants: A comprehensive review
Summary
This review examines how custom-made electrospun fiber materials — ultra-thin fibers produced by an electrical spinning process — can act as highly effective filters for removing heavy metals, agricultural chemicals, and microplastics from contaminated water and soil. The authors conclude that electrospun adsorbents remain a promising and competitive remediation technology because their structure and chemistry can be precisely tailored to target specific pollutants.
Despite a broad range of new techniques developed, adsorption methods remain one of the technologies of choice for the removal of contaminants. However, significant progress has also been made in these, which finds reflection in a new spectrum of adsorbents that can be used. This comprehensive review discusses properties, advantages, and perspectives on the use of custom-made electrospun adsorbents in the processes of heavy metals, agrochemicals, and microplastic contaminants removal from the environment. It presents the versatility and adaptability of materials that can be used as electrospun fibers matrix, also considering the mechanism and parameters of the sorption process carried out with them. The presented review proves, that due to the use of new, custom-made sorbents, such as electrospun materials, the adsorption processes still possess great application potential and development opportunities to provide an attractive and effective alternative to other remediation techniques.
