Activated carbon (AC) with porous structure is ef-
fective sorbent, very promising for water puriﬁ cation.
Carbon sorbents are used for water treatment to remove
various contaminants (heavy metals salts, chlorine) and
also for odor eliminating .
In addition to the impurities of different nature, water
also contains various microorganisms, against which the
AC is inefﬁ cient. To eliminate this drawback, bactericidal
additive, mostly silver ions, is added to the initial AC. At
the same time, another modiﬁ er, fullerenes, arouses even
growing interest in modern scientiﬁ c society owing to
From the scientiﬁ c literature [2, 3], data on the antimi-
crobial properties of fullerenes are available. The authors
of  demonstrated the antiviral activity of fullerenes
with respect to DNA and RNA viruses and to various viral
groups differing in the genome structures, morphologies
and replication mechanisms.
The water treatment processes, including those to
remove microﬂ ora, are mostly implemented in the ﬂ ow-
through mode by passage of water through the sorbent
bed. In the given case, fullerenes are attached to the
surface of the porous carrier [4, 5]. However, the degree
of change of the bactericidal activity of fullerenes upon
attachment is unclear.
In this study, attempt is made to compare bactericidal
activity of AC, fullerenes, and fullerenes attached to the
surface of carbon adsorbents.
We used in the study the AKU LV 2341 activated
carbon from coconut shells, which is commonly used
for household water ﬁ lters, and C
(containing 92 and 90% of main substance, respectively)
produced at the Innovations of Leningrad Institutes and
Plants Joint-Stock Company (St. Petersburg).
Aqueous solution of fullerenes was obtained by the
procedure developed in the St. Petersburg State Tech-
nological Institute. To do this, weighed portions of
fullerenes were mixed with 15-crown-5 ether served as
stabilizer for 5 minutes and then the resulting mixture
was dissolved in distilled water. The resulting solution
was subjected to ultrasonic treatment and stirring with a
Fullerene suspension was prepared by inserting a
fullerene sample directly into the water without using a
stabilizer and ultrasonic exposure.
The method of fullerene application onto the porous
support consisted in mixing of AC sample with an aque-
ous system containing fullerenes. The resulting mixture

Abstract—Disinfection properties of activated carbons and C
fullerenes, as introduced into the
structure of the activated carbon and in the form of aqueous dispersions, are studied. The most efﬁ cient method
was determined for the modiﬁ cation of activated carbon with fullerenes. It was shown that the presence of a
modiﬁ er intensiﬁ es suppression of microorganism growth in an aqueous medium without reducing its absorption
