The immobilization of glucose oxidase (GOx, enzyme of oxidoreductases class) was carried out on non-magnetic (SiO2, Al2O3) and magnetic mesoporous oxides (Fe3O4-SiO2, Fe3O4-Al2O3). Magnetic supports were synthesized by in-situ crystallization of magnetite nanoparticles in mesopores. The surface of the support was preliminarily modified with amino groups and the glutaraldehyde was used as a linker for covalent binding of the enzyme. The supports and biocatalysts were fully characterized using a combination of physi...

Solutions to the environmental problems associated with the burning of coal in power plants are in poor condition. One of the main problems is the continuous growth and accumulation of ash and slag waste (ASW). Ash and slag waste is a major source of raw materials for various industries. However, the degree of use of ash and slag waste at Russian thermal power plants does not exceed 2 million tons / year, with an annual output of 25-28 million tons. Modern methods of enrichment and processing allow the use of ash ...
