Adsorption of Oil by 3-(Triethoxysilyl) Propyl Isocyanate-Modified Cellulose Nanocrystals

Oil leaks into water bodies and increased organic pollutants harm the environment ecosystem in several ways, cleaning up oil spills from is a global challenge. This research aimed to construct modified cellulose nanocrystal (CNC) based aerogels with 3-triethoxysilyl propyl isocyanate (TEPIC) evaluate their potential application adsorption. Here, freeze-drying method was employed make CNC aerogels. The were characterized using scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) analysis, porosity density measurements, Fourier transform infrared spectroscopy (FTIR), contact angle (WCA) measurement, compressive strength, adsorption capacity. SEM results confirmed that have largely porous structure, including community of uniformly interconnected fibers. Moreover, studied had low due high porosity. Also, small pore diameter specific surface area by BET evaluation. FTIR existence functional groups strong hydrogen bonding between CNC/TEPCI/Urea molecules. All TEPIC-modified values greater than 130° indicating hydrophobicity. highest glycerol obtained use Thus, sample 3 wt% TEPIC showed capacities 130 ± 7.22, 120 4.75, 95.28 4.82 gg−1 for motor oil, vegetable glycerol, respectively. this study ultra-light, hydrophobic adsorbent materials on chemically can successfully be fabricated.
