In this study, a new type of molecular sieve/polyacrylonitrile fiber (M-PAN) was prepared by electrospinning to adsorb atmospheric volatile organic compounds (VOCs). The suitable content of molecular sieve in nanocomposites was also determined for achieving maximum VOCs adsorption capacity. SEM, TEM and N2 adsorption/desorption analyzer were performed for characterization of the surface morphology, structural properties, surface area and pore size. A part of molecular sieve is exposed on the fiber surface where VOCs can be adsorbed efficiently in a short time. Acetone was used as a challenge pollutant to evaluate the adsorption of VOCs at different recycling times and types of electrospinning nanofibers. The adsorption capacity of 6M-PAN (60% weight of molecular sieve) nanofiber reached 58.2 μg g−1 and the reused nanofibers nearly had the same adsorption capacity as the newly prepared nanofibers after several times of recirculation.

The paper presents the results of the development of a new type of gas analytical device for the detection of hard-volatile active organic compounds - drugs, psychotropic drugs and their metabolites, environmental pollutants. It is based on the principle of thermal desorption in combination with surface ionization of the analyte molecules under study. In studies on the detection of trace amounts (from 0.1 ng) in sample extracts, the identification of the analyte is carried out by comparing the thermal desorption spectra and determining their number of the calibration curves of the reference samples available in the electronic database of the spectrometer.

AbstractA new type of reactor which is operated with a combination of surface discharge and UV radiation emitted by a lamp discharge is studied for both its fundamental characteristics and the treatment of volatile organic compounds (VOCs). The surface discharge occurs along the wire electrode which surrounds on the outer tube of reactor and generates ozone from the air. It seems that the UV emission has an effect on the initiation and uniformity of the surface discharge. The toluene treatment in oxygen or air and argon mixture gas was carried out and the decomposition of almost 100% was established at the applied voltage of 4 kV (peak to peak). The toluene in oxygen was converted into CO
