Екологічно безпечне вилучення важких металів з природних вод за допомогою мікроводорості Chlorella vulgaris Policarp

Abstract

The work analyzes the current state of natural water pollution with heavy metals and considers the prospects of using the microalga Chlorella vulgaris Policarp strain as a biosorbent for environmentally safe removal of toxic metals (Pb, Cd, Cu, Zn, Cr, Ni, etc.). It was established that the combination of biosorption by Chlorella with magnetcontrolled technologies (modification of biomass with magnetic nanoparticles) significantly increases the efficiency of metal removal, prevents desorption and ensures rapid separation of metal-saturated biomass. The advantages of the method compared to traditional physico-chemical methods (chemical precipitation, ion exchange, reverse osmosis) are shown in terms of minimal formation of secondary toxic waste, low operating costs and the possibility of further biomass utilization (biodiesel, biogas). The highest efficiency of the method is demonstrated when integrated with the “green” synthesis of nanoparticles based on Chlorella extracts.
