摘要

Oil spills are serious environmental hazards resulting from accidents in marine or aqueous environments during petroleum well drilling and other related activities. This study presents a novel double-drying process for fabricating PUF@chitosan (CH), PUF@chitosan@activated-carbon (CAC), and PUF@chitosan@polyaniline (CPA) composites modified for oil spill cleanup, with a focus on enhancing hydrophobicity and oleophilic properties. The composites were analyzed and characterized by scanning electron microscopy (SEM) for morphology, Fourier transform infrared (FTIR) spectroscopy for functional groups, and X-ray diffraction (XRD) analysis of the crystal structure. The nanoparticle size was investigated using TEM analysis, recorded 51.33 nm, 45.61 nm, and 37.63 nm (CH), (CAC), and (CPA) respectively, which indicated the nano size of the particles. The thermal properties of the samples were assessed by thermogravimetric analysis (TGA) and the solvent compatibility of crude oil diluted with toluene, phenol, and kerosene. Diluting crude oil with phenol resulted in a higher sorption capacity of 50.50 gg-1 in the oil sorption tests. Crude oil toluene dilution exhibited a higher sorption capacity of 45.83 g g-1 and 97.38% adsorbed compared to diesel fuel in the oil-water sorption test, demonstrating the influence of solvent selectivity on the sorption performance. The effects of different solvents and the role of temperature in adjusting the viscosity of oil solutions, which subsequently affect the sorption behavior, were investigated. 60% of petroleum ether was recovered from the extracted oil. This study aims to protect aquatic life and human health by preventing the disruption of marine ecosystems.
