In this study, when Te (IV) and Te (VI) solutions were prepared by deionized water, unexpected differences in the flame AAS sensitivity for Te were found, depending on the oxidation state. Te (IV) gave a significantly greater absorbance than the same concentration of Te (VI) in the air-acetylene flame. However, when these solutions were prepared in 1.0 % (v/v) HNO(3), they had equal sensitivity for flame AAS. This behavior allows one to determine total Te without any error.

Electrochemical and chemical oxidation of K(C2H5OCS2),[Ni(C2H5OCS2)(2)] and [N(C2H5)(4)][Ni(C2H5OCS2)(3)] Dag, O; Önal, Ahmet Muhtar; Isci, H (1996-06-26) Electrochemical and chemical oxidation of (Et-Xan(-)), [Ni(Et-Xan)(2)] and [Ni(Et-Xan)(3)](-) (Et-Xan(-) = C2H5OCS2- have been studied by Cyclic Voltammetry and in situ UV-Vis spectroscopy in acetonitrile at room temperature. Cyclic Voltammograms (CV) of Et-Xan(-) and Ni(Et-Xan)(2) display one (0.00 V) and two (0.35 and 0.80 V) irreversible oxidation peaks, respectively, referenced to Ag/Ag+(0.10 M) electrode. However, CV of Ni(Et-Xan)(3)(-) displays one reversible (-0.15 V) and two irreversible (0.35, 0.80...
Activity Comparison of MCM-41 and V-MCM-4 Catalysts for Ethanol Selective Oxidation and DRIFTS Analysis Gucbilmez, Yesim; Doğu, Timur; BALCI, FATMA SUNA (2009-01-01) The activity of a V-MCM-41 catalyst with a V/Si molar ratio of 0.04 was compared with the activity of a pure MCM-41 catalyst and some DRIFTS studies were performed in order to understand the mechanism of selective oxidation of ethanol. V-MCM-41 was found to be much more active than pure MCM-41, favouring the formation of high amounts of ethylene over 300 degrees C. MCM-41, on the other hand, was found to favour the formation of acetaldehyde over ethylene at all studied temperatures. It was shown by reaction...
Catalytic oxidation of nitrogen containing compounds for nitrogen determination Karakaş, Gürkan (2019-02-15) The high temperature catalytic oxidation (HTCO) performance of Al2O3 supported Pt, Cu, Cu-Ce and Fe catalysts were systematically studied with a perspective of selective oxidation of nitrogenous compounds to nitric oxide for quantitative determination of bound nitrogen. The catalyst samples were prepared via impregnation and characterized by XRD and BET. In addition, temperature programmed reaction experiments with acetonitrile and oxygen were conducted to evaluate the catalytic activity and selectivity tow...
Thermal degradation of poly(propylene oxide) and polyepichlorohydrin by direct pyrolysis mass spectrometry Uyar, T; Hacaloğlu, Jale (2002-09-01) The thermal degradation of poly(propylene oxide), (PPO) and polyepichlorohydrin, (PECH) were studied with the use of direct pyrolysis mass spectrometry. The effects of heating rate and dissociative ionization on fragmentation pattern have also been investigated. It has been determined that PPO degrades via a random cleavage mechanism, the labile C-O bond scissions being preferred, An analogous degradation mechanism can be proposed for PECH. Yet, the elimination of side chains, evolution of HCl and the loss ...
Thermal degradation of polysiloxane and polyetherester containing benzoxazine moieties in the main chain Bagherifam, Shahla; Kışkan, Barış; Aydogan, Binnur; Yagci, Yusuf; Hacaloğlu, Jale (2011-01-01) In this study investigation of thermal characteristics of polysiloxane and polyetherester containing benzoxazine moieties in the main chain was performed via pyrolysis mass spectrometry. Pyrolysis mass spectrometry analyses revealed that the thermal stability and the extent of cross-linking enhanced when the benzoxazine moieties were separated by thermally more stable units such as siloxanes. However, when the siloxane chain units were long, possibility of polybenzoxazine growth decreased significantly and ...
