Abstract

A method for mixed two-stage modification of mineral fibers on the basis of natural basalts in various media is developed. Such processing allows achieving a substantial increase in sorption capacity of materials. The nitrogen vapor adsorption method and BET model are used to determine the specific surface area, as well as to assess the pore size distribution. It is shown that chemical leaching creates a developed system of mesopores. High sorption activity of superfine basalt fiber adsorbents against radioactive aerosols makes it possible to recommend them as starting materials for adsorption filters when creating reliable emergency air purification systems used at NPP and other enterprises with nuclear installations.
