“…The conventional methods for oil spill cleanup are booms, in situ burning, dispersant, oil skimmers, and sorbent materials according to the variation in oil types, locations, and weather conditions. [1][2][3][4][5][6] Oil spill cleanup by sorbent material is the simplest method for surrounding oil spill area by transformation spilled liquid into semisolid phase or solid phase. 7 The important properties of an ideal sorbent material for oil spill cleanup are oleophilicity and hydrophobicity, excellent oil/water selectivity, floatable before and after oil sorption, and reusable.…”

Biorenewable polyisoprene latex obtained from natural rubber, Hevea brasiliensis, was used to prepare the reusable polyisoprene-poly(alkyl acrylate) foam for petroleum-based liquid absorption. The foam was produced via latex vulcanization and cured by steaming. The effect of various types of poly(alkyl acrylate) such as poly(methyl methacrylate) (PMMA), poly(butyl methacrylate) (PBMA), and poly(butyl acrylate) (PBA) on oil sorption capacity of the foam were studied. Scanning electron microscope (SEM) images showed interconnected open-cell macrostructure with the foam porosity greater than 75% and good compression set. The oil sorption capacity of the foam was in the range of 2.0-16.6 g g 21 . The addition of poly(alkyl acrylate) enhanced hydrophobicity and oil sorption capacity of the foam. The absorbed oil was easily recovered by squeezing and the foam can be reused up to 30 sorption-desorption cycles and still preserve high quality sorption.

Oil Spill Cleanup from Sea Water by Sorbent Materials

et al. 2005

Three sorbents were compared in order to determine their potential for oil spill cleanup. Polypropylene nonwoven web, rice hull, and bagasse with two different particle sizes were evaluated in terms of oil sorption capacities and oil recovery efficiencies. Polypropylene can sorb almost 7 to 9 times its weight from different oils. Bagasse, 18 to 45 mesh size, follows polypropylene as the second sorbent in oil spill cleanup. Bagasse, 14 to 18 mesh size, and rice hull have comparable oil sorption capacities, which are lower than those of the two former sorbents. It was found that oil viscosity plays an important role in oil sorption by sorbents. All adsorbents used in this work could remove the oil from the surface of the water preferentially.

“…Another MSF material is developed by Luong et al using aluminium alloy A356 filled with silicon carbide hollow spheres (SiC) [1]. They reported that the compressive and plateau strengths were higher compared to aluminium/fly ash cenosphere metallic syntactic foam under uni-axial loading [9,10,13]. The compressive strengths of Al/SiC foams was recorded at 160 MPa, however for the Al/fly ash cenosphere this parameter was found to be only 75 MPa [10].…”
