摘要: Abstract Recently developed montmorillonite clay-based aerogels have attracted an attention owing to their highly porous internal structure. This study deals with the design of experiments applied for preparation clay aerogel polymer composites and testing optimization oil spill sorption. Three variables been chosen experimentation, i.e. amounts (MMT), polyvinyl alcohol (PVA) sodium dodecyl sulfate (SDS). Based on experimental response surface models constructed. The objective was maximize performances materials sorption dodecane motor oil. To this end, multi-objective problem has solved using NSGA-II algorithm. sorbent prepared under optimal conditions 2.109% w/v PVA, 2.678% MMT 0.210% SDS bestowed best performance both (23.63 g/g) (25.84 g/g). Finally, hydrophobic trimethoxy(octadecyl)-silane TMOS (C 21 H 46 O 3 Si). modified material disclosed good capacities (10.55 g/g) (12.25 g/g). retention profile test revealed that about 1.06–14.91% liquid hydrocarbons can be recovered by free drainage. advanced recovery oily liquids achieved centrifugation technique being 42.29–66.02%. Likewise, (modified TMOS) showed a capacity (9.24 g/g) in presence water (W-test). In addition, characterized means scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy X-ray diffraction (XRD) technique.
