In order to accurate and precise determination of Volatile Organic Compounds (VOCs) from vehicular emissions were developed method including a) adsorption of VOCs on different adsorbents followed by thermal desorption and gas chromatography (GC) with flame ionization detector (FID) quantification, b) validation of the sampling and analytical method. The adsorption efficiency of Tenax and Chromosorb 106 adsorbents were eveluated for 104 VOCs to select of adequate sorbent for passive sampling. Since most of the anthropogenic VOCs emitted from urban location are associated with the vehicle experiments were performed near road side. The results obtained showed the both the adsorbents almost same efficieny for selected VOCs emitted from vehicular exhaust. The VOC levels measured in this study were comparable with European cities and lower than Asian cities. The differences of VOC levels measured with different cities are due to traffic composition of the cities and their characteristics of fuel.

Development of novel analytical methods for selenium, gold, silver and indium determination using volatile compound generation, atom trapping and atomic absorption spectrometry Arslan, Yasin; Ataman, Osman Yavuz; Department of Chemistry (2011) A novel analytical technique was developed where gaseous hydrogen selenide formed by sodium tetrahydroborate reduction is transported to and trapped on a resistively heated gold-coated W-coil atom trap for in situ preconcentration. The atom trap is held at 165 ºC during the collection stage and is heated up to 675 ºC for revolatilization; analyte species formed are transported to an externally heated quartz T-tube where the atomization takes place and the transient signal is obtained. For gold, a high volum...
Determination of volatile organic compounds in different microenvironments by multibed adsorption and short-path thermal desorption followed by gas chromatographic-mass spectrometric analysis Oznur, Kuntasal; Deniz, Karman; Daniel, Wang; TUNCEL, SEMRA; Tuncel, Süleyman Gürdal (2005-12-16) A multiphase assurance approach was developed for the accurate and precise determination of volatile organic compounds (VOCs) in different microenvironments. This approach includes (i) development of a method including adsorption of VOCs onto a multisorbent media followed by short-path thermal desorption (SPTD) pre-concentration and gas chromatography (GC) coupled to a mass spectrometry (MS) quantification, (ii) validation of the sampling and analytical method and (iii) validation of the data using a multid...
Development of new methods for the synthesis of pyrazoles, 4-iodopyrazoles, isoxazoles and 1,2,4-oxadiazoles Kıvrak, Arif; Zora, Metin; Department of Chemistry (2011) Synthesis of five-membered heteroaromatic compounds such as pyrazoles, isoxazoles and 1,2,4-oxadiazoles are important for pharmaceutical industry and material science due to their applications. Although there are many methods to prepare such compounds, new variants continue to appear since they exhibit a wide range of biological and medicinal activities. In this thesis, new methods were developed for the synthesis of 4-iodopyrazoles, pyrazoles, isoxazoles, 1,2,4-oxadiazoles and/or 1,2,4-oxadiazepines. In th...
Investigation of extraction methodologies for quantitative determination of polycyclic aromatic hydrocarbons in sediments Topal, Tansel; Tuncel, Semra G.; Department of Chemistry (2011) The extraction procedures for the determination of polycyclic aromatic hydrocarbons (PAH) concentrations in sediment samples had been developed by using GC-FID and GC-MS. The optimized methods were soxhlet extraction, ultrasonic bath extraction and solid phase micro extraction (SPME). In order to search out the main factors affecting extraction efficiencies of the methods, factorial design was used. The best extraction method was chosen and optimum values for main factors were selected for the development o...
