USE OF MICROSCOPIC ALGAE IN ENVIRONMENTAL TECHNOLOGIES
The article presents data on technologies for treating sewage and contaminated soils using microscopic algae. A promising direction for using algae biomass to extract rare earth metals from electronic waste is shown. The ability of microscopic algae cells to extract metals is based on the processes of ion exchange, adsorption, deposition, and accumulation. To implement the method, it is necessary to conduct research to justify the type of microscopic algae, determine the conditions for biosorption, assess the toxicity of the extracted metals and their effects on the cell.
