Abstract—Sorption properties of a new composite sorbent containing Black Sea bottom sediments and oxidized
carbon produced from a natural raw material, coconuts were examined. Quantitative characteristics demonstrating
the selectivity of sorption of Cu
, and Cd
ions by the synthesized sorbent and its components were obtained.
The role played by the sorbent components in the sorption processes under study was elucidated.
The large amounts of hazardous and toxic substances
that found way into human organism with aerosols
and food predetermine the need to develop sorbents
with a pronounced selectivity of their sorption action,
and primarily that toward heavy metal ions, because
sorption methods ﬁ nd steadily increasing application in
intensive therapy of intoxication by salts of these metals
and in puriﬁ cation of aqueous solutions and technical
and industrial water [1–3].
Successful solution of a wide variety of problems of
the sorption technology requires new selective adsorbent
materials with polyfunctional exchange centers [1–3].
Recently, a new concept of enterosorption has
been successfully evolving. This concept consists in
development of new selective composite sorbents
with polyfunctional ion-exchange centers [4–7] and
production of mechanical formulations by taking in
strictly deﬁ ned proportions adsorbents of fundamentally
different nature, e.g., oxidized carbon , which is
a weakly acid cation exchanger with a complexation
function, and natural clayey minerals possessing
properties of selective inorganic cation exchangers .
Previously, composite sorbents have been produced
(Ultrasorb, Carboxicam ) in which properties of two
and more components are successfully combined. When
absorbing hazardous substances, heavy metal ions, and
radionuclides, composites of this kind simultaneously
normalize the basic biochemical parameters of an
organism , and the components of a combine sorbent
mutually supplement each other.
A conclusion was made in  that bottom sediments
(BSs) can be used in a mixture with carbons produced
from natural raw materials (crushed fruit tree kernels,
KAU) as medicinal preparations and bactericidal means
necessary for detoxication of an organism to remove
organic contaminants and toxic metals and in water
Studies have been carried out [12–15] of the mineral
chemical composition of natural mineral bottom
sediments and their structural-sorption and bactericidal
properties and methods for sorption recovery of heavy
metal ions and organic dyes by the bottom sediments
under study, in comparison with activated carbons and
certain clayey sorbents.
It has been shown that the intensity of these processes
is primarily determined by the physicochemical
properties of a composite, its structural characteristics,
and sorption capacity for substances being absorbed,
and the ﬁ nal properties of a composite sorbent (CS)
depend on the relative amounts of its components and
