Abstract

Sorption properties of nanostructured powders of aluminum oxide, obtained by EB PVD at condensation temperatures 100-650° С, with respect to positively charged metal ions and negatively charged ions of non-metals with different ionic and atomic radius were studied.

A comparative study of the adsorption capacity of nanostructured aluminum oxide, depending on the structural characteristics of the obtained materials revealed that it adsorbs predominantly positively charged metal ions. It appears that high sorption capacity of the nano-alumina takes place with ion or atom radiuses increased. However, the adsorption of anions does not depend on the structure of aluminum oxide.

It is revealed that nanostructured alumina can adsorb and retain on its surface metal and nonmetal ions, which makes it a promising material for water purification.
