Colloid-Chemical and Nanochemical Processes in Peloids on Basis of Ferrous Clay Minerals

Influence of colloid-chemical and nanochemical processes (aided with nanoparticles of montmorillonite and calcium carbonate which are containing in bentonites) on compositions from ferrous clays and deepwater marine clay-containing peloids (used as medical muds) were examined. XRD, SEM, and rheological methods were used for colloid-chemical investigations and a method of testing biological activity of peloids and peloid compositions on white Wistar rats was used for balneological studies. It is shown that natural bentonite which consists of 90 % of montmorillonite, 4 % of CaCO3 and 6 % of quartz sand has almost no influence on their balneological properties. Otherwise, addition up to 15 % of burnt at 600 °C bentonite increases balneological activity of peloid compositions in 2–3 times. It occurs due to formation of nano- and microparticles during rehydration processes. Same influence on peloid composition balneological properties is shown for nanoparticles of calcium carbonate. But on the other hand, carbonate and montmorillonite microparticles included in bentonite composition has almost no influence on balneal indexes of peloids. The mechanisms of studied processes are discussed in the article below.
