Introduction. The relevance of the study is due to the need to search for environmentally safe and economically feasible sorbents for wastewater treatment from organic pollutants, in particular, oil and petroleum products. The purpose of the work is to study the sorption properties of fibrous waste from the flax processing industry and evaluate the effectiveness of their plasma modification. Methods. The empirical basis of the study was made up of samples of flax bonfires before and after low-temperature plasma treatment in a high-frequency generator. The sorption capacity of materials in relation to oil was studied under static conditions. The kinetics of the sorption process was analyzed by constructing logarithmic functional dependencies using the least squares method (OLS). Results. It was found that plasma modification can significantly increase the sorption capacity of flax bonfire due to the development of its specific surface area and an increase in the number of active centers. Mathematical models have been obtained that adequately describe the kinetics of oil sorption by the original (R2 = 0.998) and modified (R2 = 0.997) linseed. It is shown that the relative error of the models does not exceed 0.03%. Discussion. The results of the work open up prospects for the use of plasma-modified flax bonfire as an effective and environmentally friendly sorbent for the elimination of oil spills and post-treatment of industrial wastewater. It is advisable to direct further research to optimize the parameters of plasma processing, as well as scaling the process.
