Abstract—Interaction of ozone with microfibrous materials based on polystyrene, acrylonitrile, diacetylcellulose,
vinyl chloride and carbon are studied by the methods of IR Fourier and Raman spectroscopy.
This work continues investigations [1, 2] of the
properties of microﬁ brous ﬁ lter materials in respect to
ozone decomposition. In  the activity of various ﬁ lter
materials has been compared at the interaction with
ozone. In  by the methods of electronic and atomic
force spectroscopy structural changes in ﬁ lters under the
action of ozone have been investigated.
The aim of this work is the study of the changes in
chemical composition of ﬁ lter material after treatment
with ozone and of chemical composition of the formed
gaseous substances. The practical signiﬁ cance of such
investigation consists in estimation of thr possibility of
application of industrial ﬁ lter materials for the puriﬁ cation
of air from ozone. Such investigation can also be
interesting for understanding the mechanism of ozone
elimination by various ﬁ lter materials.
For the elucidation of changes in the chemical
composition of the polymer ﬁ lter structure after the
action of ozone we applied the vibration IR absorption
spectroscopy (IRS) and for the ﬁ lters based on carbon, the
Raman spectroscopy. The results obtained are compared
with the published data on the ozone interaction with
polymers constituting the ﬁ ber material of the ﬁ lter
samples. The IR spectra of all the polymers examined
in this work have been well studied [3–8]. The results
published in the literature were obtained with the powders,
ﬁ lms and bulk samples. It is interesting to compare those
results with the data obtained from the microﬁ brous ﬁ lters
of the same composition.
We examined industrial Petryanov’s ﬁ lters based on
the styrene – acrylonitrile copolymer FPSAN-70-0.5,
diacetlcellulose FPA-15-2.0, perchlorovinyl FPP-70-
0.5, as well as the experimental materials based on
polyacrylonitrile FPAN-10-3.0, polystyrene FPS-15 and
carbon microﬁ bers. The ﬁ rst numerical in the name of a
ﬁ lter means average ﬁ ber diameter expressed in tenths
of micron, the second one shows the air ﬂ ow resistance
expressed in the water column height (mm) at the airﬂ ow
1 cm s
. By their activity in ozone decomposition the
ﬁ lter materials form the following sequence: FPS-15 >
FPSAN-70-0.5 > carbon ﬁ ber > FPA-15-2.0 > FPP-70-0.5
> FPAN 10-3.0 .
