“…[46][47][48] In addition, acetone, acetic acid, and formaldehyde have also been identified in the NTP decomposition of toluene. 49 According to these previous results, CH 2 In the subsequent experiments, the gas-phase organic by-products were quantified by PTR-TOFMS to give a more precise evaluation of the NTP technique. Figure 6 displays the concentration variations of toluene and corresponding organic by-products in real time (resolution = 1 second) under plasma off and plasma on conditions.…”

“…Volatile organic compounds (VOCs) include pure to partially oxidized hydrocarbons and chlorine, sulfur, or nitrogen‐containing hydrocarbons, and are recognized as major contributors to air pollution because of their toxicity and their involvement in the formation of tropospheric ozone and photochemical smog. Some VOCs are very hazardous to human health and the environment . Current available techniques for VOC removal from air are UV/O 3 , electron beam, photocatalytic oxidation, biofiltration, and the Fenton reaction .…”

Proton transfer reaction mass spectrometry (PTR-MS) is a mature technique for the real-time measurement and monitoring of volatile organic compounds in the atmosphere. In this paper, a modified quantification method for PTR-MS was used to assess the performance of nonthermal plasma (NTP) reactor for the removal of toluene which was widely used in industrial production processes. Toluene and 11 corresponding organic by-products were tentatively identified and quantified by a proton transfer reaction time-of-flight mass spectrometer. The degradation dynamics of toluene and the formation of organic by-products were monitored in real-time (resolution = 1 second) under "plasma off" and "plasma on" conditions. We conclude that initial concentration and gas flow rate were the key parameters in the health risk assessment of NTP for the removal of toluene. The toluene removal efficiency and CO selectivity decreased with increasing upstream toluene concentration or gas flow rate, whereas the health risk influence index increased with increasing upstream toluene concentration or gas flow rate. The highest removal efficiency of toluene (100%), CO selectivity (53.2%), and the best health risk influence index for organic by-products (0.11) were achieved when the toluene concentration was kept at 105 ppmv and flow rate at 0.4 L/minute. The results demonstrate that PTR-MS is a promising tool to improve the practical applications of volatile organic compound removal by NTP because it can be used to optimize the NTP working conditions by providing a precise, fast, and clear health risk assessment for organic by-products based on their real-time analysis.

“…Volatile organic compounds (VOCs) usually refer to organic compounds with boiling points less than or equal to 250 • C at atmospheric pressure and high vapor pressures (above 0.1 mm Hg) at room temperature [1,2]. Among the different types of VOCs, aromatics play an important role in stratospheric ozone depletion as well as aerosol and smog formations [3] and have adverse effects on human health [3].…”

A novel strategy for toluene abatement was investigated using a sequential adsorption-regeneration process. Commercial Hopcalite (CuMn2Ox, Purelyst101MD), Ceria nanorods, and UiO-66-SO3H, a metal–organic framework (MOF), were selected for this study. Toluene was first adsorbed on the material and a mild thermal activation was performed afterwards in order to oxidize toluene into CO2 and H2O. The materials were characterized by XRD, N2 adsorption-desorption analysis, H2-TPR and TGA/DSC. The best dynamic toluene adsorption capacity was observed for UiO-66-SO3H due to its hierarchical porosity and high specific surface area. However, in terms of balance between storage and catalytic properties, Hopcalite stands out from others owing to its superior textural/chemical properties promoting irreversible toluene adsorption and outstanding redox properties, allowing a high activity and CO2 selectivity in toluene oxidation. The high conversion of toluene into CO2 which easily desorbs from the surface during heating treatment shows that the sequential adsorption-catalytic thermal oxidation can encompass a classical oxidation process in terms of efficiency, CO2 yield, and energy-cost saving, providing that the bifunctional material displays a good stability in repetitive working conditions.

“…It is a compound identifiable by an unpleasant smell with a potential to form carcinogenic nitrosamines in the air after emitted for a certain period. The use of such a coating on a structure for an extended period risks exposing people to the emitting VOC (Censullo et al, 2003;Dinh et al, 2016;Eklund & Nelson, 1995). Hence, researchers have developed a variety of techniques to measure the amount of VOCs emitted by coatings and established the corresponding standards to decrease the risk of detrimental health effects on humans.…”

A large number of anti-corrosion coatings containing volatile solvents with aliphatic hydrocarbons, formaldehyde and benzene are produced annually with the risk of releasing harmful volatile organic compounds (VOCs) into the air. In this study, a commercial coating product for protecting steel is compared with the newly formulated green coating for the quantification of VOC content. The comparison was executed using the mass difference method following ASTM D2369-03. The extract and formulated coating were also subjected to optical, electrochemical and morphological studies, ie, Fourier Transform Infrared (FTIR) Spectroscopy, Ultraviolet-Visible (UV-Vis) Spectroscopy, Electrochemical Impedance Spectroscopy (EIS) and Scanning Electron Microscope/Energy Dispersive X-Ray (SEM/EDX). Based on the extract characterization, functional groups of hydroxyl, carboxylic acid and carbonyl with wavenumbers of 3350.cm -1 , 2947.23 cm -1 and 1053.13 cm -1 , respectively were identified. Also, coating with 3 wt.% of Leucaena leucocephala leaves extract (LLE), P2 showed a consistent optimum performance in reducing corrosion until the 40 th day with a rate of 3.14 x10 -3 mm/year. The P2 sample was later subjected to VOCs content analysis, and the outcome displayed a lower VOCs content of 345.40 g/L compared to a commercial product, which fulfilled the standard requirement for low-VOC paint by the Environmental Protection Agency (EPA). Hence, it can be concluded that the developed green anticorrosion coating possessed low VOCs content with excellent abilities in protecting steel exposed to an aggressive environment.
