Abstract
Due to their good price, availability and, above all, high adsorption capacity, mineral materials compete with other types of adsorbents used to remove petroleum pollutants. The research indicates that hydrophobization processes have a large impact on the improvement of the mineral sorbents functional properties, when sorbents are used to remove oil pollutants in the water and soil environment. The paper presents the process of hydrophobization of expanded vermiculite with the use of stearic acid vapour. The obtained results indicate a great influence of the hydrophobization processes on the improvement of the functional properties of vermiculite. Water absorption for the raw sorbent decreased after modification from the level of 7.23 to 5.6 g/g. After the modification process, the sorption capacity of oil compounds increased twice.
