【 摘 要 】

The construction industry requires the emergence of new promising technologies. This stimulates the creation of modern building materials, which have an expanded set of functional properties. Such materials ensure ecological compatibility of the rooms of constructed buildings and structures. One of the main sources of air pollution is building materials, structures and products. They account for up to 80% of the chemicals found in the air of the rooms in operation. The development of materials capable of absorbing toxic substances is a promising direction in the construction industry. Absorption of toxic products from the air can be achieved by the use of effective, obtainable sorbents. Among such sorbents is a group of natural zeolite-containing minerals. The article presents the results of a study to determine the activity and sorption capacity of modified zeolites of the Hotynets deposit, bentonites of the Tarasovskoye deposit. A comparative evaluation of the ways of sorbent activation is given. The mineralogical and chemical composition of the investigated zeolites, the results of the action of a low-temperature nonequilibrium plasma on the structure of natural aluminosilicates are presented. As a result of the action of a low-temperature nonequilibrium plasma, the sorption capacity of both zeolites and bentonites increased. Modification of low-temperature non-equilibrium plasma maximizes the efficiency of natural zeolite-containing rocks, which makes it possible to expand their functional capabilities. The use of low-temperature nonequilibrium plasma is an economically and environmentally beneficial method.
