Effect of Low-pressure High-frequency Plasma on Sorption Characteristics of Alternative Oil Sorbents

The possibility of using wastes from processing of agricultural raw materials, wood, and wood biomass components as alternative oil sorbents for removal of oil films from water surface is shown. It was established that treatment of these sorbents with chemical reagents (on the example of rye straw) increases sorption capacity for hydrocarbons and reduces water absorption. Treatment of sorption materials based on various lignocellulosic raw materials with low-pressure high-frequency capacitive plasma in an argon–methane atmosphere was carried out. It is concluded that plasma modification of alternative oil sorbents (on the example of pine cones) increases maximum oil absorption and efficiency of oil film removal from water surface, while reducing water absorption during oil spill response.
