PRODUCTION OF MAGNETICALLY CONTROLLED BIOSORBENTS BASED ON FUNGI Agaricus bisporus AND Lentinula edodes

The aim of the study was to produce magnetically controlled biosorbent based on fungi of champignon and shiitake, to determine the proportion of the magnetically controlled phase of the biomass of fungi when the magnetic fluid (MF) was added to the substrate and to explore the efficiency of extraction Fe3+ ions by shredded biomass of the fungus. The object of the study was mushrooms champignon Agaricus bisporus and shiitake Lentinula edodes grown in the laboratory. An effective and cheap way to remove waste biosorbent from the working environment is a high-gradient magnetic separation (HGMS), which takes place in high-speed mode. The separation of the magnetically controlled phase of fungi biomass A. bisporus and L. edodes was carried out by HGMS methods. It was investigated that when using the biomass of champignon grown on MF, the properties of the sorbent were significantly improved, the full saturation was 6 times faster in comparison with the biosorbent based on the biomass of the fungus grown without MF.
