Abstract
Thus, the basic physical and chemical properties ( moisture content (57,19 %), unit weight (1,31), shear stress (821,59 Pa), stickiness (1839,81 Pa), debris particles with a diameter of more than 250 mkm (0,34 %), specific heat (2,75 kG/(kg · K)) bentonite deposits Dashukovskoho Cherkasy region meets the eligibility criteria of the Therapeutic muds (peloids). The chemical composition of the aqueous extract of clay deposits Dashukovskoho refers to magnesium sulphate-bicarbonate-calcium-sodium type or complex cation composition with mineralization of 0,26 g/dm3. pH of the extract of clay is 7,95 m. pH is characterized by slightly alkaline reaction. Positive values oxidation -reduction potential of the extract of clay (+ 465 mV) indicate the presence of oxidative processes. This is because the clay extraction in the preparation of the latter was in contact with oxygen. It should be noted that the calculation of the structural formulabentonite is great information because it allows to introduce the character of isomorphic substitutions in the structure, efficiently detect the composition of exchange cations, which makes it possible to predict the behavior of the sample during its processing technology.
