description: The work determines the efficiency of purification of model solutions from heavy metal ions (Zn, Cd, Pb, Cu, Fe) using Lemna minor. The objects of study are duckweed Lemna minor, which was collected in Sosnovka Park, coordinates of the collection site (60.022310, 30.351073). Problems that were solved during the study: - Conduct a literature review on the research topic, - Select the mode of sorption of heavy metals using biosorption materials, - Calculate environmental damage ; - Scanning microscopy to study the structure of duckweed; - Calculate environmental damage. To solve the problems, the following methods were used: 1. Spectrophotometric method for determining the concentration of iron ions. 2. Voltammetric method for determining the concentration of heavy metal ions (zinc, cadmium, lead, copper). 3. Scanning microscopy for studying the structure of duckweed The work was carried out on the basis of the laboratory of the Higher School of Biology and Production of St. Petersburg Polytechnic University. The sorption process mode for maximum absorption of ITM using Lemna minor was determined as follows: time â 1 hour, temperature â 25 Â°C, pH 7, sorbent mass â 5 g at a model solution concentration of 5 mg/l. Using the Ta-Lab voltammetric analyzer, we saw that the highest extraction efficiency was for cadmium ions and amounted to 99.96%. The work used Microstructural studies of the residual biomass of the duckweed Lemna minor were carried out on the basis of the âCollective Use Center (CCC) âMaterials Science and Diagnostics in Advanced Technologiesâ of the Federal State Budgetary Institution of Science, Physico-Technical Institute named after. A. F. Ioffe RAS. This facility for collective use was created on the basis of the Physico-Technical Institute named after. A. F. Ioffe, funded by the Ministry of Education and Science of Russia (project number RFMEFI62117X0018).
