Ozone Conference in Russia
The First Russian Conference “Ozone and Other
Environment Friendly Oxidants: Science and
Technologies” was held at the Chemistry Department
of M.V. Lomonosov Moscow State University June 7-
9, 2005 The Conference was devoted to the 250th
anniversary of Moscow State University.
255 participants took part in the Conference. Apart
from Russian participants, scientists from Ukraine,
Belarus, Latvia, Kyrgyzstan, Bulgaria, Poland and
Singapore took part in the Conference. The Program
of the conference included 9 plenary lectures
concerning various aspects of ozone application, 83
oral reports and 37 poster presentations.
Four sections on the different aspects of ozone
application were organized in the Conference. The
first section was devoted to synthesis and analysis of
ozone, ozone generator configurations, processes and
apparatus. In the second section “Scientific
elaboration and ozone technologies” reports with a
technological character were presented. These reports
were related to ozone application in hydrometallurgy,
agriculture, organic synthesis and other
manufacturing. Ecological problems resolved by
means of ozone as well as ozone application for water
treatment and wastewater purification were also in the
scope of the third section. The forth section was
completely devoted to ozone application in medicine.
As to the plenary lectures in the first place we would
mark the lecture of Dr. S.D. Razumovskii’ “Reactions
of Ozone with Aromatic and Poly-conjugated
Systems”. The influence of the minor differences in
the structure of a number of allied aromatic
hydrocarbons on the reaction with ozone was studied.
The mechanism of ozone reaction with the similar
structure of fullerenes C60 and C70 is not the same.
The presence of the substitutes in the aromatic
structures enlarges the amount of the primary and the
secondary products. So, besides the molecular
channels of labile intermediates transformations the
radical and the chain-type processes take place.
The excellent lecture of Ph.D. K.V. Kozlov “Modern
Insight to Mechanism of Barrier Discharge in Oxygen
Page 18
– Nitrogen Mixtures” in the popular and at the same
time in the scientific form gave the account of the
modern insight into the detailed mechanism of the
barrier discharge in oxygen and in air.
The lecture of Dr. S.N. Tkachenko (M.V. Lomonosov
Moscow State University, Chemistry Department)
“Homogeneous and Heterogeneous Ozone
Decomposition” was devoted to the regularities of
photochemical, thermal and catalytic ozone
decomposition. The field of ozone decomposition
occurring on oxide cement-containing catalyst (COC)
was determined both under high and low temperatures
in the flowing reactor filled by COC granules. The
mechanism of ozone decomposition on the surface of
COC was proposed. The process was found to be
limited by the desorption process of the reaction
product (oxygen) from the surface. In the work were
determined the lifetimes of adsorbed oxygen and
ozone molecules. The heat emanation induced by
ozone destruction on COC covering the bead-type
thermistors was also simulated. The rate constants of
the principle stages of the heterogeneous ozone
decomposition on Mn - Cu catalysts were evaluated in
the work.
The lecture of Dr. N.M. Lihterova and co-authors
addressed the role of ozone in relation to processing of
heavy petroleum raw materials by ionizing irradiation.
The investigations revealed that the pre-ozonation has
changed the mechanism and the route of the radiolysis
reactions, completely. At the same time the changes of
the colloid structure of the heavy petroleum raw
materials were observed. Besides, the drastic decrease
in vanadylporphyrine concentration also took place.
Probably the following investigations in this way could
allow development of new technology of petroleum
raw materials treatment.
It is necessary to draw attention to the lecture of Prof.
V.A. Maximov and A.G. Kulikov concerning the
principle achievements in ozonetherapy. The authors
considered the possibilities of this new perspective
method of the medical treatment of a number of
diseases (atherosclerosis, diabetes mellitus, hepatitis,
ischemic insult, ulcer of the stomach, osteomyelitis
and also in cosmetology).
As regards to the section reports we would like to draw
attention to the several most interesting works. In the
first section the numerous reports informed about the
