“…Solidifiers are generally dry, granular, hydrophobic organic polymers that react with oil to form a monolithic solid that floats on water [21,22]. The formed solid can be easily removed from the water surface.…”

Application of Mineral Sorbents for Removal of Petroleum Substances: A Review

et al. 2017

Environmental pollution with petroleum products has become a major problem worldwide, and is a consequence of industrial growth. The development of sustainable methods for the removal of petroleum substances and their derivatives from aquatic and terrestrial environments and from air has therefore become extremely important today. Advanced technologies and materials dedicated to this purpose are relatively expensive; sorption methods involving mineral sorbents are therefore popular and are widely described in the scientific literature. Mineral materials are easily available, low-cost, universal adsorbents and have a number of properties that make them suitable for the removal of petroleum substances. This review describes recent works on the use of natural, synthetic and modified mineral adsorbents for the removal of petroleum substances and their derivatives from roads, water and air.

“…Spilled oil may be removed using physiochemical or microbiological means. The former approach comprises the use of sorbents [ 2 , 3 ], solidifiers [ 4 , 5 ], dispersants [ 6 , 7 ], and gelators [ 8 , 9 ]. However, the use of these products is not always environmentally safe and may even cause additional pollution [ 1 , 10 ].…”

Raw, domestic sewage of Kuwait City contained about 10 6 ml −1 colony forming units of Enterobacter hormaechei subsp. oharae (56.6%), Klebsiella spp. (36%), and Escherichia coli (7.4%), as characterized by their 16S rRNA-gene sequences. The isolated coliforms grew successfully on a mineral medium with crude oil vapor as a sole source of carbon and energy. Those strains also grew, albeit to different degrees, on individual -alkanes with carbon chains between C 9 and C 36 and on the individual aromatic hydrocarbons, toluene, naphthalene, phenanthrene, and biphenyl as sole sources of carbon and energy. These results imply that coliforms, like other hydrocarbonoclastic microorganisms, oxidize hydrocarbons to the corresponding alcohols and then to aldehydes and fatty acids which are biodegraded by -oxidation to acetyl CoA. The latter is a well-known key intermediate in cell material and energy production. E. coli cells grown in the presence of -hexadecane (but not in its absence) exhibited typical intracellular hydrocarbon inclusions, as revealed by transmission electron microscopy. Raw sewage samples amended with crude oil, -hexadecane, or phenanthrene lost these hydrocarbons gradually with time. Meanwhile, the numbers of total and individual coliforms, particularly Enterobacter, increased. It was concluded that coliform bacteria in domestic sewage, probably in other environmental materials too, are effective hydrocarbon-biodegrading microorganisms.

“…In particular, benzene and benzo(a)pyrene are a major environmental concern because they can be injurious to public health, especially when supply sources are affected (Ramalho, Aquino Sobrinho, Anjos, Dantas, & Silva, 2014;Rengarajan et al, 2015;Alegbeleye et al, 2017). In this context, several techniques have been proposed and used for cleaning and recovery of areas contaminated by oil spills, such as physical methods (Crick, Bhachu, & Parkin, 2014), chemical methods like in situ burning and solidifiers (Mullin & Champ, 2003;Rosales, Suidan, & Venosa, 2010;Sundaravadivelu, Suidan, Venosa, & Rosales, 2016), and bioremediation (Bamforth & Singleton, 2005;Crisafi et al, 2016). Among the physical methods, sorption has been widely used in oil leakage because it is simple and efficient (Wahi, Chuah, Choong, Ngaini, & Nourouzi, 2013;Boni, Oliveira, Souza, & Souza, 2016;Patowary, Pathak, & Ananthakrishnan, 2016;Yin, Zhang, Liu, Li, & Wang, 2016).…”

Biosorbents have emerged as an alternative to remove organic contaminants because they are natural products with a high availability, low cost, biodegradability, and good sorption capacity. The Mandacaru (Cereus jamacaru DC) was investigated as sorbent of diesel, and compared with the Mandacaru modified with microemulsions. The sorbents were also submitted to a physycal-chemical characterization for FT-IR, TG/DTG, MEV and CHN-O. The granulometry range 500-150 µm of the Mandacaru particulate, this was the granulometry range chosen as the standard one, being used in the modification and sorption tests. The unclassified Mandacaru presented a medium sorption capacity of the diesel oil of 1.61 g g-1. Whereas the Mandacaru modified with a microemulsion comprised of direct micelles (oil/water) showed a remarkable increase in the sorption capacity of 80-111% (3,08 to 3,54 g g-1).
