Nanosized SnO2 and CoFe2O4 composite materials: Their preparation, properties and sorption activity
2010
Nanosized SnO2 and CoFe2O4 oxide powders were obtained by mechanochemical synthesis from salt systems of appropriate reagents. Their physicochemical properties and absorption abilities were investigated with respect to microorganisms and organic impurities. The value of adhesion of Micrococcus albus and Pseudomonas putida bacterial cells amounted to 99.999–100% upon the filtration of microbial oil-contaminated suspension via columns filled with the nanosorbents under investigation. A well-developed specific surface area makes it possible to use nanosorbents to extensively rid drinking water of microorganisms and organic contaminants, which is of great importance for decreasing infectious human morbidity.
