【 摘 要 】

In this paper nanopowders obtained by vacuum spray method were studied. The phase composition of the obtained powders is γ - Al2O3. Obtained nanopowders have specific surface area about 200 m2/g. Adsorptive properties of these powders were studied by static adsorption from solutions. The anionic dye eosin was selected as adsorbate. It has been found that the powders obtained by vacuum spray method have significant capacity to adsorb eosin.
