Abstract—The structure-sorption properties of the bottom sediments and their compositions with the KAU
carbon modiﬁ ed with K
, and Zn
cations, which were synthesized for the ﬁ rst time, were studied.
The adsorption data were used to calculate the surface fractal dimension for composites under study and their
constituents. The rheological curves of the composites synthesized in a wide range of the shear rates were
obtained. The effect of their composition on the structure-mechanical properties (viscosity) of the sorbents
The main goal of the study was the development of new
application sorbents, cosmetic agents, and enterosorbents
on the basis of mineral and biological complexes of sea
bottom sediments and of a KAU carbon prepared from
fruit kernel and modiﬁ ed with K
, and Zn
In this study the physicochemical (rheological) properties
of the initial components and combined preparations
(Karbodon) obtained by them were analyzed by the
The development of new competitive and efﬁ cient
compositions, in which cheap and readily available
natural raw materials such as bottom sediments, mud,
and sludge are used as the basic component, is urgent
and promising [1−4].
Previously, the mineral and chemical composition
and the structure-sorption and bactericidal properties
of the mineral bottom sediments taken from the Black
sea were studied and the methods of sorption extraction
of heavy metal ions and organic dyes by them were
analyzed in comparison with activated carbons and
clays. A conclusion was made that the bottom sediments
in combination with KAU oxidized carbons specially
modiﬁ ed with the ions of vital microelements can be
used as medical preparations and bactericidal agents for
puriﬁ cation of human body from organic pollutions and
toxic metals and for the water puriﬁ cation .
Indeed, the first search tests  showed that the
development of such composite materials is appropriate
and necessary. Note, the synthesis of the above
composites involves the same methods, which were
used for Ul’trasorb  and Karboksikam , whose
properties are known.
Preparations selectively binding radionuclides, heavy
metals, and organic pollutants [10, 11] must contain
modiﬁ ers to regulate overall mineral balance .
Therefore, for possible correction of the microelement
composition of the salts in the human body, we used
in this study KAU oxidized carbon containing certain
amounts of the exchangeable cations, K
. Their presence and the dosed introduction,
using the ion-exchange method, into the body (i.e., under
the conditions of the established cation-anion balance)
is necessary to reach the best therapeutic effect in the
sorption therapy of serious diseases, which are hardly
treatable or cannot be treated at all by the traditional
methods. The preparation of the ionic forms of KAU
carbons, the mechanisms of therapeutic effect of the
bottom sediments, and the factors responsible for their
therapeutic and antimicrobial properties have been
described in detail in .
