Influence of sodium chloride,carbonates, and iron hydroxides on the viscosity of aqueous suspensions of clay minerals

The influence of sodium chloride solutions containing carbon dioxide on the viscosity of a maximally destroyed structure of suspensions of hydromica, kaolinite, natural iron-containing polymineral carbonate clay, iron oxides, and freshly prepared and dried montmorillonite is studied. The effect of physicochemical transformations of finely dispersed carbonates on the surface structure of a dispersed phase in suspensions of clay and iron oxide particles is considered. On the basis of the obtained results, a colloidochemical model for the destruction of ground barriers of storage ponds for mineralized water under the conditions of catastrophic phenomena is specified.Translated from Kolloidnyi Zhurnal, Vol. 67, No. 1, 2005, pp. 32–37.Original Russian Text Copyright © 2005 by Kovzun, Kovalenko, Protsenko.
