Spills of oil and its processing products on the water surface are one of the pressing environmental problems. Adsorption is an effective and efficient way to eliminate hydrocarbon spills from the water surface. However, the industrial grades of oil sorbents used have some drawbacks, such as their not always high sorption capacity, high cost, and lack of availability in the areas of spills, among others. In this regard, a new approach to the elimination of hydrocarbon spills from water surfaces is being developed worldwide: the use of cellulose-containing waste from wood processing and agricultural production as oil sorbents.In this work, the possibility of using waste from the processing industry – pea grain shells (PGS) as alternative oil sorbents for removing oil films from the water surface was investigated. Some physico-chemical parameters of the native and after ultrasonic treatment of the PGS samples were studied. The values of the maximum oil capacity in relation to the oils of the devonian and carboniferous deposits, as well as the maximum water absorption, were determined.It was revealed that the ultrasonic treatment of PGS contributes to a certain increase in the maximum oil capacity and a decrease in the water absorption of the studied sorption material. Studies were conducted on the removal of oil films from the water surface using native and modified PGS samples. It was shown that the modification of PGS enhances the removal of oil from the water surface by increasing the hydrophobicity of the material due to the extraction of water-soluble biopolymer fragments during the ultrasonic treatment process.
