Fluoride emission factors
(2002)An attempt was made to generate fluoride emission factor data for a fast- and single-fired ceramic floor-tile kiln located in Turkey. Desired emission factors were calculated from stack-gas measurements and mass-balance ... -
Treatment of gaseous trichloroethylene by a sequential (biological/chemical) reactor system
(2004)The treatment of gaseous trichloroethylene (TCE) by biotic and abiotic removal mechanisms in a sequential (biological/chemical) reactor system was investigated. The reactor system consisted of a granular anaerobic mixed ... -
Laboratory development and field evaluation of a new diffusive sampler to collect nitrogen oxides in the ambient air
(Springer-Verlag Berlin, 2002)Diffusive samplers for the determination of NOx and NO2 based on collection on a coated carbon paper filter have been developed. NO is first oxidized to NO2 and then collected on the reactive surface. When NO2 and NOx ... -
Optimum conditions for the precipitation of chitosan oligomers with DP 5-7 in concentrated hydrochloric acid at low temperature
(Elsevier Sci LTD, 1999)Chitosan was partially hydrolysed with 35% hydrochloric acid for 2 h at 80 degrees C and the hydrolysate stored at - 20 degrees C after dilution with water to precipitate higher molecular weight (MW) chitosan oligomers. ... -
Comparison of methods for estimating carbonaceous BOD parameters
(Selper LTD, Publications Div, 2001)The performance of seven different methods (Differential, Fujimoto, Thomas, Graphical, Integral, Log-Difference, and Nonlinear Regression) for estimating first-stage, carbonaceous biochemical oxygen demand (CBOD), curve ... -
Electrocoagulation of synthetically prepared waters containing high concentration of NOM using iron cast electrodes
(Elsevier Science BV, 2007)The aim of this investigation is to evaluate the treatibility of synthetically prepared water with high concentration of humic substances by electrocoagulation in batch mode using iron cast electrodes. Effects of applied ... -
Studies on electrochemical disinfectant production using anodes containing RuO2
(Springer, 2005)The present work contains results for artificial water electrolysis in discontinuous operation using laboratory reactors without separators. Rotating anodes with mixed oxide coatings containing IrO2/RuO2 were used. The ... -
Kinetic studies on electrochemical antimony removal from concentrated sulfuric acid systems
(Wiley-V C H Verlag GMBH, 2007)The aim of this study was to separate antimony from its acidic aqueous solution with an electrochemical method by cathodic deposition. For this purpose it is essential to know the electrochemical behavior of antimony. ... -
Adsorption Properties of Activated Carbon From Wild Plant Prepared By Chemical Activation
(Gh Asachi Technical University Iasi, 2015)Activated carbon was prepared from renewable plant material, that is Euphorbia rigida, by chemical activation using zinc chloride as activating reagents. The adsorption of Basic Blue 9 (BB9) onto activated carbon was ... -
Characterization of the leachate in an urban landfill by physicochemical analysis and Solid Phase Microextraction-GC/MS
(Springer, 2006)The aim of this study is to evaluate extensively the characterization and identification of major pollutant parameters by paying attention to the organic chemical pollution for unregulated dumping site leachate in ... -
Characterization of an urban landfill soil by using physicochemical analysis and solid phase microextraction (SPME)-GC/MS
(Springer, 2007)We have aimed at characterizing top soil samples taken in-situ from five different locations of the unregulated dumping site in Eskisehir/Turkey for a period of six months. The study is the first attempt in the city and ... -
Life Cycle Assessment of Waste Tire Pyrolysis
(Parlar Scientific Publications (PSP), 2015)In this study, in order to provide the input for decision-makers in Turkey, the environmental impact of a waste tire pyrolysis plant was researched using the Life Cycle Assessment (LCA) method. The functional unit is defined ... -
Electrocoagulation of olive mill wastewaters
(Elsevier Science BV, 2006)An attempt has been made to remove chemical oxygen demand (COD) from olive mill wastewaters (OMW) as well as oil-grease and turbidity in the presence of H2O2 and polialuminum chloride (PAC), as a coagulant-aid by an ... -
Electrochemical desulfurization of waste gases in a batch reactor
(Asce-Amer Soc Civil Engineers, 2007)To meet the increasing need for reduction of exhaust emissions from stationary sources, many technologies have been developed to remove SO2 from flue gas. In this study the anodic oxidation of sulfur dioxide in aqueous ... -
Effects of surface oxidation and oxygen on the removal of trichloroethylene from the gas phase using elemental iron
(Kluwer Academic Publ, 2003)The reduction of trichloroethylene (TCE) in the gas phase by Fedegrees was examined under water vapor saturated conditions (relative humidity (RH) = 100%). The reaction conformed to first-order rate kinetics under anaerobic ... -
Accumulation of sulfur and heavy metals in soil and tree leaves sampled from the surroundings of Tuncbilek Thermal Power Plant
(Pergamon-Elsevier Science LTD, 2004)In this study, the quantities of sulfur and heavy metals, resulting from the Tuncbilek Thermal Power Plant (TPP) in Turkey, have been assessed in tree leaves and soil samples within a 10 km radius of the plant. Leaves of ... -
An evaluation of the bottom ashes from healthcare waste in a laboratory scale incinerator: Microbiology, mutagenicity and toxicity
(Parlar Scientific Publications (PSP), 2006)In this study, experiments of healthcare waste incineration at 500, 600, 700, 800 and 900 degrees C in a lab-scale incinerator were carried out, performing different total bacterial counts for the microorganisms in bottom ... -
