There were no mico- and spore-forming bacteria, yeasts, actinomycetes, and
streptomycetes. Glauconite was the most effective for treatment of dexamethasone
arthrosis and endogenic intoxication.
In addition to stated advantages, it was proven that tested clays and peloids with
their content are effective for state correction of hemophilic genic-broken blood
coagulation due to their chemical composition (presence of iron and microelements)
and extremely high adsorption ability [29].
Conducted investigations of bentonite and glauconite in modeling conditions of
their biogeocenosis impacted influence on properties of more complex materials –
peloids and pelagic sediments, allowed to conclude that their physicochemical
properties’ changing correlates with nanostructure-and-nanochemical clay mineral
transformations with oxide and silicate compounds of iron – Schemes (13.1,
13.2, 13.3 and 13.4). The latter ones are connected respectively with changing of
therapeutic properties of peloids and clays in peloid composition.
13.4 Conclusions
Investigation was made of the processes of nanochemical structuration in ironoxide-hydroxide-silicate systems aided with biogeocenosis by using peloid sediments, peloids and clays in peloid composition – bentonitic and glauconitic,
using physicochemical, colloid–chemical, and biological methods, and theoretical concepts of physicochemical and classic geomechanics. It was shown that
nanochemical structuration of such systems and sediments is limited by metabolic
processes of microorganisms, first of all iron-reducing ones and autotrophic bacterium producing surface-active substances. These bacterial reactions induce transformation of Fe 3+ micro- and macroparticles of iron-contained minerals into
nanoparticles and nanoclusters of Fe 2+ hydroxides. The latter are chemically or
microbiologically transformed under the influence of CO 2 and ± 2 from air into
unstable nanostructured layered double hydroxides (LDX) of Fe 2+ · Fe 3+ (green
rust) of GR(CO 3
2− ) type. Chemical LDX transformation at further interaction
with O 2 from air results in forming of nanogoethite (α- FeOOH), which structures
disperse minerals by general Scheme (13.4) in contact zones of micro- and colloid
particles of silicate or alumino-iron-silicate minerals by interactions (13.1, 13.2, and
13.3). In so doing, there are new iron-oxide-hydroxide systems with new properties
being formed. It is shown that along with the general process there are also clay
minerals contained in iron-oxide-silicate systems, peloid sediments, and peloids
taking part in structure transformations. For bentonite and glauconite the processes
of their structuration in peloid sediment composition were modeled according
to concepts of physicochemical and classical mechanics and geomechanics. It is
shown that rheological processes in concentrated clay and clay–pelloid suspensions
are characterized by abnormal flow character and viscoplastic properties close to
Atterberg plasticity limit. The mechanism of such process was determined. It is
shown that clay minerals not only have influence on properties for practical use of
