The possibilities of the oil spill cleanup from the water environment are presented. Mechanical methods of oil recovery are described—the oil containment booms, oil skimmers, and use of sorbents. The sorption capacity of various sorbents is compared based on laboratory tests according to the ASTM F726 methodology. The results of the determination of residual oil pollution of water after the cleaning process are presented. The properties of the absorption sock during the sorption of crude oil and the oil/water mixture were also presented.

“…Various chemicals have been used for oil spill remediation, e.g., surfactants, nanoparticles, biosurfactants, and ionic liquids [9][10][11][12][13][14]. Over the last two decades, several types of nanoparticles have been efciently applied to oil spill remediation, e.g., titanium dioxide, magnetite, graphite, graphene, carbon nanotubes, and hydrophobic organoclay [14,15].…”

Oil spills in marine environments are a serious environmental concern and using low-cost materials for oil spill cleanup is an emerging subject. In recent years, surface-modified magnetite nanoparticles (MNPs) have shown promising properties for oil spill cleanup due to their high performance, low cost, magnetic properties, and reusability. This study aims to modify the surface of magnetite nanoparticles (MNPs) using two new polyamines and employ them for oil spill remediation. First, tetraethylene glycol (TEG) was converted to the corresponding alkyl halide (AH). Next, two polyamines were synthesized via the alkylation of diamines, 1,11-undecanediamine (UD) and 1,5-pentanediamine (PD), yielding the corresponding AH-UD and AH-PD polyamines. Finally, AH-UD and AH-PD were applied to MNPs’ surface modification, yielding the corresponding surface-modified MNPs, AU-MNPs, and AP-MNPs. The performance of AU-MNPs and AP-MNPs for oil spill uptake (OSU%) was investigated using various MNPs-to-oil ratios at different contact times. Furthermore, the reusability of AU-MNPs and AP-MNPs was also investigated over four cycles. The results indicated that the OSU values of AU-MNPs and AP-MNPs were affected by MNPs’ ratios and contact time, where their OSU increased as their ratios and contact time increased. In addition, AU-MNPs showed a higher OSU than AP-MNPs, which could be ascribed to the longer alkyl chain in the polyamine (AH-UA) used for their surface modification compared to AP-MNPs. Furthermore, AU-MNPs and AP-MNPs reusability results exhibited effective OSU in four cycles with a relative decline with an increasing number of cycles.

The development and operation of new oil fields on the Arctic shelf increases the risks of oil spills, which require the use of oil spill response tools and materials that are efficient in harsh climatic conditions. The question of actual efficiency of sorbents for reducing the level of oil pollution in the conditions of the Arctic and subarctic waters is relevant. The work is aimed at a comparative study of the efficiency of sorbents of mineral and organic origin used by coastal enterprises in the Kola Bay as well as a sorbent based on chitin in model systems simulating real conditions in sea waters. The characteristics of sorption agents were determined applying ASTM F716-18 procedure. Sorption capacity was evaluated in respect of ARCO grade oil, diesel fuel and marine oil. The efficiency of sorbents was estimated in model systems “sea water – oil” at water temperature corresponding to the average annual surface temperature in the Barents Sea. Actual data on sorption capacity of commercial sorbents “Lessorb”, “Novosorb”, a sorbent based on vermiculite and chitin sorbent in relation to potential pollutants of waters were obtained. The dynamics of sea water saturation with oil products at –0.5 (±1) and 10 (±1) °С was determined. It is shown that at higher temperature the concentration of oil products in sea water column (in the presence of an oil film on the surface) is on average four times higher than at low temperature. Kinetic dependences were obtained that describe the content of oil products in water column and near-surface layer of sea water in the presence of the studied sorbents at 5 (±1) °C, corresponding to the average annual temperature in the Kola Bay of the Barents Sea. A method is proposed for evaluating the efficiency of sorbents from the values of regression coefficients characterizing the dependence of oil products content in sea water on the character of sorbent and duration of its action.
