Analcime-bearing rocks as advanced sorbents

The rational use of water and soil resources and their effective purification are actual scientific problems for modern society. Inexpensive and effective natural sorbents, zeolites, are widely used to solve environmental problems and improve the safety of the use of water and soil resources. This article presents results of our study of the sorption properties of analcime-bearing rocks in the north-east of the European part of Russia. Experiments and analytical studies were carried out using modern analytical equipment. The high sorption activity of these rocks with respect to radioactive elements (uranium, radium, thorium) was established. The simulated biogeosorbents based on analcime-bearing rocks and target microorganisms exhibited high sorption and destructive properties to oil products and phenols, ensured preservation and increased the growth of Chlorella vulgaris microalgae cells under stress conditions: with increased salinity and exposure to organic pollutants.
