Ion-exchange properties of the granular and powder fractions of Sokyrnytskij clinoptilolite as for calcium and potassium under the chemical modeling of human stomach (0,1 M HCl) and intestine (solution of NaHCO3 pH 8,5) are analyzed by flame-photometric and X-ray fluorescent methods. It is shown that the powder fraction has better ion-exchange properties than the granular fraction. Adsorption of lead (II), zinc (II), manganese (II) and cadmium (II) is studied under the chemical modeling of human stomach. The powder fraction has better adsorptive properties than the granular fraction. In 0,1 M HCl, it removes 85 % of Pb(II), ions of Zn(II) and Mn(II) on the level 0,2 - 0,6 of their maximum allowed concentration in drinking water, and does not remove cadmium (II).

Ion-exchange properties of shungit (Kareliya, Russia) and saponit clay (Khmelnytskii region, Ukraine) under conditions of the chemical modeling of human stomach (0,1 M HCl) and intestine (solution of NaHCO3, pH 8,5) are analyzed by IR-spectroscopy and X-ray fluorescence methods. Adsorption of lead (II), zinc (II), manganese (II), iron (III), copper (II), and cadmium (II) is studied by flame-adsorption and X-ray fluorescence methods under selected conditions. It is proved that these minerals are safe and useful as the filling agents of alimentary components and medicinal preparations from the chemical point of view.
