“…The absorption band became more obvious when the system moved from the sol-to-gel state, which proved that there are multiple conjugated systems. Therefore, the bathochromic shift of the absorption band (from 218 to 219 nm) due to the conjugation effect of the carbonyl group formed a large π bond (Ghosh et al 2016;Raza et al 2020;Zhang et al 2022).…”

“…Marine oil spills and industrial oily wastewater discharge could cause irreversible destruction to the environment as well as lead to resource waste and huge economic loss (Rajendran et al 2022;Zhang et al 2022). There are large amounts of toxic substances in oils, which bring serious health problems to marine organisms and human society (Chen et al 2019;Denic-Roberts et al 2022;Zhong et al 2021).…”

Rapid and effective recovery of the oil spill is extremely challenging during oil spill remediation. To meet this challenge, an organogelator-polymerized porous matrix composed of adsorbents and organogelators provided a new strategy. This work investigated the gelling mechanism of aluminum 12-hydroxystearate (Al HSA) to form spherical nano micelles in solvents via UV-vis, FT-IR, and XRD. We creatively proposed a method for saponification of 12-hydroxystearic acid (HSA) on lignin via epichlorohydrin (ECH) crosslinking to produce aluminum soap-lignin gelator (OTS-AL/Al HSA). By adjusting the ECH content, Al HSA nanoparticles (15-40 nm) were grown on lignin, which improved the roughness endowing lignin with better hydrophobicity (WCA 134.6°) before octadecyltrichlorosilane (OTS) modification. Oils and organic solvents could be rapidly adsorbed by OTS-AL/Al HSA gelator at low temperatures due to the abundant pore structures. Rheological studies demonstrated its gelation characteristics, which were attributed to the rapid absorption of oils by lignin and the self-assembly of Al HSA nano micelles on lignin to form an aggregated network structure trapping oils, thus realizing the synergistic effect of oil adsorption-gelation. Recyclable materials, easy preparation process, and excellent oil treatment capacity make this new biomaterial may inspire more research in oil spill remediation in the future.
