Validation and use of a new diffusive sampler for ozone assessment in the Lazio Region, Italy
(2002)To monitor the effect of control measures for ozone it is desirable to map the concentrations for this pollutant at regional level, in agreement with the aims of the European Framework Directive on ambient air quality ... -
Integrated preventive environmental management training for municipalities: A case study from Turkey
(2003)[No abstract available] -
Removal of nitrate from aqueous solutions by electrodialysis
(2002)In this work the removal of the nitrate from water was carried out by electrodialysis. In the experiments the effect of the applied voltage, pH value, initial nitrate concentration and duration of treatment on the removal ... -
Fluoride injury in some regional plants grown in the vicinity of Bozuyuk ceramic factories and fumigation chamber studies
(1996)Within the scope of this study, the culture plants barley (TOKAK) and wheat (GEREK 79) species grown in the agricultural fields nearby Akpinar Region in the vicinity of Bozuyuk Ceramic factories, were planted in flowerpots. ... -
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 ... -
Fluoride in ceramic materials
(2004)Fluoride contents in ground soil, water, wastewater samples and some coal samples were investigated. It was observed that naturally occurring fluoride in these environments is ?200ppm for solids and ~1.3 mg/L for seawater. ... -
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 ... -
Electrochemical removal of antimony from spent battery acid - Part 2 [Elektrochemische antimonentfernung aus akkumulatorsäure: Teil 2 - Ergebnisse kinetischer untersuchungen]
(2005)Part 2 reports electrode kinetic studies based on anodic stripping from rotating disk electrodes made of platinum, glassy carbon, copper and antimony. With all of these, the deposition of antimony or its oxide could be ... -
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 ... -
Comparison of two regression techniques for the estimation of contaminant loadings to streams
(2005)The study describes two simple methods to estimate contaminant loads from point and diffuse sources and to separate groundwater and surface contributions to streams and compares the results of two regression techniques ... -
The formation of chlorine dioxide in the electrochemical treatment of drinking water for disinfection
(Pergamon-Elsevier Science LTD, 2005)There are increased activities in development and application of electrochemical disinfection cells using the natural chloride content for disinfectants production by directly electrolysed water. Unfortunately, the process ... -
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 ...
