This study reports on the fabrication of a hydrophobic sponge aerogel from pomelo peel for oil/water separation. The synthesized HPSA-1 showed medium absorption capacity for oils and organic solvents, with absorption saturated at exposure times of 10 s. It was found that HPSA-1 had higher absorption capacity for diesel oil and palm oil.
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.
