Abstract
Nanosized powders of the oxides SnO2 and CoFe2O4 with the specific surface of 130 and 160 m2/g, respectively, were obtained by means of mechanochemical synthesis from the salt systems of the corresponding reagents. The physicochemical characteristics of the powders and their absorption ability with respect to microorganisms and organic pollutants were studied. It was established that the sorption of bacterial cells Microccocus albus and Pseudomonas putida during filtration of the microbial oil-polluted suspension through the columns filled with the nanosorbents under investigation is 99.999-100 %. Due to the developed specific surface, the nanosorbents can be used for high-quality purification of drinking water from microorganisms and organic pollutants, which is important in the effors to decrease the infectious morbidity of the population.
