HIGHLIGHTS OF OIL TREATMENT TECHNOLOGIES AND RISE OF OIL-ABSORBING MATERIALS IN OCEAN CLEANING STRATEGY

Nowadays, the problem of oil pollution is becoming a big challenge for the environment. Oil pollution threatens the survival of life on land as well as aquatic life. Aware of the seriousness of oil pollution, there have been many scientific studies on solutions to oil spill treatment. The methods can be mentioned as mechanical treatment, microbiological treatment, chemical treatment, absorbent material treatment. Each method has its advantages and disadvantages. In this short review, recent research activities related to the selection of oil-absorbing absorbents and their application in oil absorption are presented. Then, an extensive list of different oil-absorbing materials from the literature, including polymeric materials, porous inorganic materials, and biomass materials, was provided along with their characteristics. Furthermore, the oil adsorption capacity of such materials for different oils and organic solvents has also been discussed to highlight different factors involved in the selection of adsorbent adsorbents. Oil has been tested to separate oil in oil-water mixtures. Finally, some future trends and prospects for oil-absorbing materials are outlined.
