The single-pellet moment technique was shown to be a powerful method for investigating the diffusion and adsorption of volatile hydrocarbons in the soil. The technique was used to evaluate effective diffusivities, adsorption equilibrium, and rate constants of chlorinated hydrocarbons (monochloroethane, 1,2-dichloroethane, 1,1,1-trichloroethane, and 1,1,2-trichloroethane). Results obtained in a dry system showed that adsorption rate constants of all these hydrocarbons on the soil pellet used are of the same order of magnitude (4.4-8.0 cm3 g-1 s-1). On the other hand, molecules having chlorine atoms bonded to the same carbon atom (monochloroethane, 1,1,1-trichloroethane) have adsorption equilibrium constants about 1 order of magnitude smaller than these for molecules containing chlorine atoms bonded to different carbon atoms (1,1,2-trichloroethane, 1,2-dichloroethane).

Determination of the dispersion of supported Pt particles by gas-phase and liquid-phase measurements Kivrak, Hilal; Mastalir, Agnes; Kiraly, Zoltan; Üner, Deniz (Elsevier BV, 2009-02-15) The dispersion of a Pt/gamma-Al2O3 catalyst was investigated by various experimental techniques. The values obtained by gas-phase hydrogen and carbon monoxide adsorption and transmission electron microscopy (TEM) were consistent for the metal:adsorbate stoichiometry of 1:1. However, these methods overestimated the number of active sites available for a liquid-phase reaction. For the hydrogenation of styrene in the presence Of CS2 as a catalyst poison, only the defect sites were found to be active in the cat...
Characterization of humic materials extracted from hazelnut husk and hazelnut husk amended soils Cimen, Funda; Ok, Sonay Sozudogru; Kayran, Ceyhan; Demirci, Şahinde; Ozenc, Damla Bender; Ozenc, Nedim (Springer Science and Business Media LLC, 2007-06-01) This study was carried out to determine effects of composted hazelnut husk (CHH) on some chemical properties of soil and soil humic acid (HA). Compost application increases organic matter (OM) content of the soil considerably, OM value of 3.18% became 3.89% in 3 years time interval. Before application of compost, the soil pH was found to be 5.37, while after compost application it became 5.61. FTIR characteristics of humic acid/humic acid-like materials extracted from the original hazelnut husk, composted h...
Preparation and characterization of carbon supported platinum nanocatalysts with different surfactants for C1 to C3 alcohol oxidations Ertan, Salih; Gökağaç Arslan, Gülsün; Department of Chemistry (2011) In this thesis, carbon supported platinum nanoparticles have been prepared by using PtCl4 as a starting material and 1-octanethiol, 1-decanethiol, 1-dodecanethiol and 1-hexadecanethiol as surfactants for methanol, ethanol and 2-propanol oxidation reactions. The structure, particle sizes and surface morphologies of the platinum were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM) and transmission electron microscopy (TEM). XRD and TEM results indicate that all prepared catalysts have ...
The inhibitory effects of lindane in batch and upflow anaerobic sludge blanket reactors Bayramoğlu, Tuba Hande; Demirer, Göksel Niyazi (Elsevier BV, 2003-01-01) In this study, the inhibitory effects of lindane (LIN) on originally unacclimated mixed anaerobic cultures were investigated by anaerobic toxicity assay (ATA) experiments. ATA experiments revealed that 10 mg/l LIN exerted inhibitory effects on anaerobic cultures, which was recoverable. Continuous reactor experiments conducted to determine the inhibitory effects of LIN and the maximum LIN loading rate achievable in two-stage upflow anaerobic sludge blanket (UASB) reactors indicated that anaerobic granular cu...
Comparison of TOC concentrations by persulphate UV and high temperature catalytic oxidation techniques in the Marmara and Black Seas Tuğrul, Süleyman (Elsevier BV, 1993-01-01) Total organic carbon (TOC) concentrations were determined in the Marmara Sea and both oxic and anoxic waters of the Black Sea, using the Shimadzu high-temperature catalytic oxidation technique and the Technicon persulphate-UV oxidation method. The TOC values in the deep waters of the Marmara Sea ranged between 60 and 73 μ MC by the Shimadzu technique and from 40 to 50 μMC by the Technicon method. The TOC values obtained by both methods in the deep anoxic waters of the Black Sea varied between 105 and 130 μM...
