Concentrations of environmental radioactivity in sediment cores from kulakcayiri lake
(Turkish Chemical Society, 2018)
This paper is about measurements of environmental radioactivity in samples taken from a lake bed and from different depths. The study is based on gamma spectrometric analysis of some radioisotopes encountered in sediment ...
Investigation of Inland Pollution Using Total Carbon (Tc), Total Organic Carbon (Toc), Inorganic Carbon (Ic), Total Nitrogen (Tn) and Toc/Tn Ratios
(Corvinus Univ Budapest, 2019)
In this study, sediment samples were taken at three different points in Edremit Bay at different depths from the sea floor. In Edremit Bay, it was investigated whether the pollution was marine or terrestrial. According the ...
EFFECT OF CALCINATION CONDITIONS ON PARACETAMOL PHOTODEGRADATION BY METAL (Zn, Ag, Fe) DOPED TiO2 CATALYSTS
(Parlar Scientific Publications (P S P), 2017)
The aim of this study was to evaluate paracetamol photodegradation by metal (Zn, Ag, Fe) doped TiO2 process and also examine the effects of metal/TiO2 ratio and catalyst preparation parameters on paracetamol degradation. ...
Removal of antibiotics in a parallel-plate thin-film-photocatalytic reactor: Process modeling and evolution of transformation by-products and toxicity
(Science Press, 2017)
Photocatalytic degradation of sulfamethoxazole (SMX) antibiotic has been studied under recycling batch and homogeneous flow conditions in a thin-film coated immobilized system namely parallel-plate (PPL) reactor. Experimentally ...
Comparative Assessment of Sludge Pre-Treatment Techniques to Enhance Sludge Dewaterability and Biogas Production
(Wiley, 2018)
Effectiveness of ultrasonication, microwave technologies, and enzyme addition prior to anaerobic digestion is investigated using sludge samples taken from the secondary settling tank of a domestic wastewater treatment plant ...
Visible light active N-doped TiO2 immobilized on polystyrene as efficient system for wastewater treatment
(Elsevier Science Sa, 2017)
The photocatalytic activity of N-doped TiO2 particles supported on polystyrene (PS) surface by using a solvent-cast method at ambient temperature was evaluated on methylene blue (MB) dye decolourization. Subsequently, the ...
Investigation of the chlorine dioxide disinfection in terms of disinfection by product (DBP) formation of Omerli raw water in Istanbul
(Pamukkale Univ, 2017)
Chlorine which is nowadays the most commonly used disinfectant, interacts aquatic organic matter and causes formation of harmful disinfection by products. For this reason, number of researches on chlorine dioxide as a ...
An investigation of anthropogenic pollution in soil samples from residential areas in Erzincan city center and its vicinity by evaluating chemical factors
(Springer Heidelberg, 2018)
To measure heavy metal pollution, 42 different soil samples were collected and analyzed from the center, cities, and villages of Erzincan. Average element concentrations in the soil samples in micrograms per gram were as ...
Manganese adsorption by iron impregnated pumice composite
(Elsevier Science Bv, 2017)
Manganese (Mn) is often present at high concentrations in ground and surface waters. Industrial discharges are also a major source of Mn pollution in the environment. Adsorption is a widely studied technique to abate Mn ...
Assesment of Chemical Tretability of Fur-Suede Processing Wastewater Together with Toxicity Removal
(Yildiz Technical Univ, 2018)
