Abstract
X-ray diffraction analysis data has been used to calculate the electron-density distribution of a squared crystal of hydrated antimony pentoxide during sorption of water, nitric acid, and strontium cations. It has been shown that absorption of water and acid molecules causes reversible changes of the anionic framework of the ionite. Sorption of divalent cations is accompanied by irreversible phase transformations in the sorbent structure, which is also the cause of the particularly strong retention of particles of the material absorbed.
