| Popis: | The sorption properties of chitosan granules – the residual biomass of microalgae Chlorella Sorokiniana – that are formed after the extraction of valuable components from them (lipids, pigments, pectins) are studied. A literature analysis of the use of microalgae, chitosan and materials based on it for the purification of water from various pollutants has been carried out. The technique for obtaining chitosan granules – residual biomass is described, and their sorption properties are studied during the treatment of wastewater from iron(III) ions. The efficiency of wastewater treatment of iron(III) ions by chitosan granules is calculated – residual biomass, which for solutions with an initial concentration of 5 mg/l, it was 88 %. Microstructural studies of the surface of chitosan-residual biomass Chlorella Sorokiniana granules were carried out and their physicochemical and mechanical properties were studied. A comparative analysis of granules with DAK grade coal is given. It is shown that mechanical properties (abrasion, grindability) meet the requirements of GOST R 51641-2000. A technological scheme for the production, use and disposal of chitosan granules-residual biomass of Chlorella Sorokiniana is proposed. |
