Oil spills and industrial oily wastewater pose serious threats to the environment. A series of modified membranes with special wettability have been widely used for separating oil/water mixtures emulsions. However, these still face challenges such as detachment coatings membrane fouling. Here, a freestanding biobased superwetting nanofibrous mixture separation was electrospun chitosan (CS) poly(vinyl alcohol) (PVA) precursors, followed by chemical cross-linking in situ growth β-FeOOH nanoparticles on surface. Moreover, precisely controlling both time between CS PVA nanoparticles, nanosize apertures rough structures surface can be regulated toward wide range scenarios. As result, FeOOH@CS/PVA-4–12 demonstrated superwettability, water contact angle 9.5 ± 3.5° air an underwater–oil above 140°, achieving efficiency 98.5% permeation flux 2350 L·m–2·h–1 n-heptane/water mixtures. The FeOOH@CS/PVA-24–24 exhibited exceptional oil-in-water emulsion performance up 99.9% water/n-heptane Additionally, remarkable antifouling properties, attributed its photocatalytic ability nanoparticles. After five self-cleaning cycles, remained almost unchanged, demonstrating great potential practical application.

The presence of dyes and heavy metals in wastewater represents a significant environmental public health hazard, necessitating the development efficient materials for their removal. In this study, we modified hydrolyzed polyacrylonitrile (PAN-H) combined it with β-cyclodextrin (β-CD) by using an electrostatic spinning technique to fabricate composite nanofibrous membranes water treatment applications. resulting PAN-H/β-CD nanofiber exhibit spindle-shaped fibers porous structures high density charged functional groups, which significantly enhance selective adsorption capacity compared pure PAN fibers. Furthermore, post-treatment sodium bicarbonate solution further improved capacity, demonstrating remarkable efficiency cationic dyes. process conformed Langmuir pseudo-second-order kinetic models, maximum capacities 216.94 mg/g methylene blue (MB), 471.59 malachite green (MG), 299 crystal violet (CV), 43.95 copper ions. these positively contaminants, particularly metallic copper, indicates that have potential containing similar pollutants.
