background: the incomplete burning of fuel in engine of vehicles, evaporation of petrol from gas stations, and also car carburetor cause unburned hydrocarbons to be emitted in ambient air of cities and gas station locations. from unburned hydrocarbons; monocyclic aromatic hydrocarbon influence to citizen's health and benzene is known as carcinogenic compounds. the objectives of this study are t...

In order to evaluate the adsorption potential of multi-walled carbon nanotubes (MWCNTs) for benzene, toluene and xylenes (BTX), the adsorption capacities of benzene and toluene on two different MWCNTs were measured using a gas-chromatography (GC) and then compared with each other. Fourier transform infrared (FTIR) was employed to investigate the presence of f...

Plastic costume masks regularly exhibit unpleasant odors that may be associated with the emissions of volatile organic compounds (VOCs). Upon inhalation, VOCs might adversely affect wearer’s health if exposure exceeds regulatory threshold values. The emitted from a selection (n = 12) were characterized semiquantitatively screening method based on GC/MS measurements in dynamic headspace sampling...

Abstract In this study, the composition of tars collected during a six-day underground coal gasification (UCG) test at experimental mine ‘Barbara’ in Poland 2013 was examined. During test, tar samples were taken every day from liquid product separator and analysed by methods used for testing properties typical coke oven (coal) tar. The obtained results compared with each other data As progresse...

Volatile organic compounds (VOCs) are ubiquitous pollutants in surface water, which is the main source of drinking water South Korea. We investigated behavior (concentration, distribution, and environmental risk) eleven selected VOCs Han River tributaries using purge-and-trap gas chromatography/mass spectrometry. The average concentration was 0.29 ± 0.47 ?g/L. Chloroform trichloroethylene (TCE)...

Separation of hydrocarbon molecules, such as benzene/cyclohexane and o-xylene/m-xylene/p-xylene, is relevant due to their widespread application chemical feedstock but challenging because similar boiling points close molecular sizes. Physisorption separation could offer an energy-efficient solution this problem, the design synthesis sorbents that exhibit high selectivity for one hydrocarbons re...
