Biodegradable electrospinning superhydrophilic nanofiber membranes for ultrafast oil-water separation

Science Advances, Journal Year: 2023, Volume and Issue: 9(34)

Published: Aug. 23, 2023

Although membrane technology has attracted considerable attention for oily wastewater treatment, the plastic waste generated from discarded membranes presents an immediate challenge achieving eco-friendly separation. We designed on-demand biodegradable superhydrophilic composed of polylactic acid nanofibers in conjunction with polyethylene oxide hydrogels using electrospinning ultrafast purification water. Our results showed that use increased number hydrogen bonds formed between surface and water molecules by 357.6%. This converted hydrophobic into ones, which prevented fouling accelerated emulsion penetration through membranes. The oil-in-water permeance our newly nanofiber 61.9 times (2.1 × 104 liters per square meter hour bar) separation efficiency >99.6%, was superior to state-of-the-art Moreover, formation found accelerate biodegradation lactic over 30%, offering a promising approach treatment.

Waterborne heavy metals pose significant threats to both the environment and public health, causing neurological damage, developmental disorders, organ cancer. It is essential address contamination of various water bodies by these hazardous substances due their persistent nature lack biodegradability. This review thoroughly explores traditional modern strategies utilized remedy sources contaminated with evaluates effectiveness potential scalability each method. A literature survey reveals several effective for removing from water: adsorption, flotation, ion exchange, chemical precipitation, membrane-based filtration, coagulation, flocculation, phytoremediation, electrochemical methods. In our examination, we discussed agents/adsorbents used, efficiency removal technique, operating conditions, intrinsic advantages disadvantages approach. Summarizing key findings, noted a focus on adsorption techniques; however, challenges include selectively diverse ions, prolonged retention times, cycling stability. While membrane methods are practical, issues like large-volume sludge formation exist. Although electrical-based appear promising, solutions needed industrial-scale separation as well. Prioritizing real wastewater samples in studies crucial. Future research should emphasize eco-friendly, cost-effective
