Oil Spill Cleanup from Sea Water by Porous Sorbents

Abstract

Sorbents were produced on the basis of rice husk, rubber crump and apricot stone by carbonization. They all possessed a high sorption capacity for oil and oil products. With the use of these sorbents an oil overflow was experimentally removed from the surface of the river Syrdarya (Kyzylorda). Results showed that the oil sorption capacities of carbonized rice husk, rubber crumb and apricot stone were 18, 14 and 7 g/g, respectively. The material obtained by carbonization of rice husk has very good buoyancy characteristics, high oil sorption capacity and high hydrophobicity. The effects of contact time, water temperature, amount and type of sorbents on the oil sorption capacity of the carbonized sorbents were further studied on the basis of microstructure and morphology using optical digital microscopy and scanning electron microscopy (SEM). The results of the SEM and optical microscopy studies strongly indicate that carbonization is a suitable method for improving the porous structure of the sorbents particles compared to the virgin samples. This research provides the basis for the development of a new environmental material with optimal characteristics, providing efficient sorption of oil and oil products from an aqueous medium.

Preparation of highly interconnected porous polymer microbeadsviasuspension polymerization of high internal phase emulsions for fast removal of oil spillage from aqueous environments

“…14 Among these technologies, adsorption by oil absorbents is considered to be one of the most efficient techniques, and has distinct advantages of simple operation, low cost, and complete cleanup without secondary pollution. [15][16][17][18] Interconnected porous resins with hydrophobicity and lipophilicity are preferential candidates for oil absorption because of their outstanding oil-water selectivity, high absorption capacities, fast absorption kinetics, excellent reusability, and oil recovery. 19 As is known to all, the templating of high internal phase emulsions (HIPE) is an effective method to prepare highly interconnected porous polymeric materials, oen referred to as polyHIPEs, which possess ultra-high permeability.…”

“…C, Fe, Cu, Zn, Mn, Cr, Ca, K, Ti, Cl, S, Ni, Si were found. This fact corresponds to the reference data [10][11][12][13][14][15][16][17][18][19]. Unmodified BS samples and composite materials obtained on its base were investigated by EDAX method in order to establish their elemental composition.…”

“…Some Kazakhstan scientists investigate RH from different regions of Kazakhstan using it mainly as an adsorbent for waste water treatment and similar purposes. [10][11][12][13][14][15], production of technical silicon [16] or for the supercapacitors [17][18]. All experiments in this study were carried out with RH, taken from the Terenuzek village, Kyzylorda region, Kazakhstan.…”
