Problems from water contamination of oil and organic solvents have become more serious in recent years. We report research describing the fabrication of a hydrophobic sponge aerogel from pomelo peel for oil/water separation. Hydrophobic pomelo peel sponge aerogel (HPSA-1) was synthesized via dispersion, freeze-drying, and chemical vapor deposition (salinization) with hexadecyltrimethoxysilane. The morphology and chemical properties of the sponge aerogels were analyzed by scanning electron microscope and Fourier transform infrared. HPSA-1 was examined for use to remove some oils and organic solvents floating on water. HPSA-1 aerogels had medium absorption capacity; however, removal ability and the absorption of HPSA-1 were saturated at exposure times of 10 s. Diesel oil was the highest absorbate with absorption capacity (3.08–3.64 g g−1) and recovery percent of 48.15–59.46%. Removal abilities of selected oils and organic solvents floating on water using HPSA-1 at 10 s were investigated. HPSA-1 absorbed the oils and organic solvents in the range of 1.98–3.85 g g−1, with absorption levels depending on their types. Of the oils tested, palm oil had the highest absorption level with HPSA-1 removal at 3.85 g g−1 and 57.5%, respectively. [ABSTRACT FROM AUTHOR] |
