Article
A novel and environmentally friendly three-liquid-phase extraction (TLPE) approach was developed for simultaneous separation of copper (Cu), magnesium (Mg) and zinc (Zn) from water samples. The proposed organic/two aqueous phase system consists of di(2-ethylhexyl)phosphoric acid (D2EHPA), Choline Chloride:urea (deep eutectic solvent (DES)), and sal...
Article
Background: Chocolate is a rich source of essential and non-essential elements. A new liquid-liquid extraction approach, extraction induced by emulsion breaking (EIEB), is proposed in which the analyzed elements are transferred from the organic phase to the aqueous phase before measurement by flame atomic absorption spectrometry (FAAS). Objective...
Article
Background The emulsion induced by emulsion breaking (EIEB) procedure was previously reported for the extraction of copper, iron, manganese and nickel from liquid oil samples such as vegetable oil. Objective To optimize the EIEB procedure for determination of copper, iron, manganese and nickel in solid oil (margarine) samples by Graphite Furnace A...
Article
In this study, the quantification of macro, micro and toxic elements in milk and its products was carried out using inductively coupled plasma optical emission spectrometry (ICP-OES) after using sample preparation procedures (wet digestion, dry digestion, and microwave digestion). Samples were collected from farms and markets in Edirne, Turkey. Ca,...
Article
ABSTRACT The concentrations of cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) were determined in five (Nettle, Linseed, Pumpkin seed, Sesame, and Chamomile) herbal oil samples, using inductively coupled plasma atomic emission spectrometry (ICP OES) after ultrasonic extraction (UE), wet dig...

The concentrations of cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) were determined in five (Nettle, Linseed, Pumpkin seed, Sesame, and Chamomile) herbal oil samples, using inductively coupled plasma atomic emission spectrometry (ICP OES) after ultrasonic extraction (UE), wet digestion (W...
Article
In the present study, concentrations of calcium (Ca), copper (Cu), magnesium (Mg), manganese (Mn), sodium (Na), and zinc (Zn) in hardaliye samples produced in Turkey were determined by flame atomic absorption spectrometry after ultrasound probe extraction (UPE), microwave-Assisted extraction (MAE), and wet extraction procedures. At present, there i...
Article
In this work, a new procedure using extraction induced by emulsion breaking (EIEB) procedure has been developed for extraction/preconcentration of cadmium in various edible oils (canola, corn, hazelnut, olive, and sunflower oil) prior to its determination by flow injection (FI) flame atomic absorption spectrometry (FAAS). Five chemical variables (s...
Article
A new procedure using extraction induced by emulsion breaking (EIEB) procedure has been developed for extraction/preconcentration of zinc in various edible oils (canola oil, corn oil, hazelnut oil, olive oil, and sunflower oil) prior to its determination by the single line flow injection (FI) flame atomic absorption spectrometry (FAAS). Several par...
Article
Sorghum-agricultural waste in nature (SAWN) and chemically activated with phosphoric acid (SAWAC) was used as a solid phase extraction material for determination of cadmium, copper, manganese and lead ions in aqueous solutions by flame atomic absorption spectrometry (FAAS). The effect of pH, sample flow rate and volume, eluent type, volume and flow...
Conference Paper
Some chemical elements found in the froth of the Philaenus spumarius and Lepyronia coleoptrata (Hemiptera: Cercopoidea). by Selcuk YURTSEVER*, Dilek BAKIRCIOGLU**, Burcu KARAHALIL* *Biology Department, Science Faculty, Trakya University, 22030 Edirne, Turkey. **Chemistry Department, Science Faculty, Trakya University, 22030 Edirne, Turkey. Corresp...
Article
An online cloud-point extraction (CPE) coupled with flow injection method is developed for the separation and preconcentration of palladium and lead from various matrices using flame atomic absorption spectrometry (FAAS). The method employs the formation of complexes of the metallic species with dimethylglyoxime, which are subsequently entrapped in...
Article
A syringe‐connected minicolumn (SCM) technique has been developed for preconcentration and enrichment of cobalt, iron, and lead in river‐water samples prior to their determination by flame atomic absorption spectrometry (FAAS). The proposed technique is substituted for the classical batch and column techniques all of which are off‐line methods. The...
Article
Coliform bacteria physically immobilized on titanium dioxide nanoparticles can be used as a biosorbent for solid phase extraction of lead (II) ions from aqueous solution using a flow injection system coupled to flame atomic absorption spectrometry (FAAS). Effects of pH value, sample volume, flow rates of loading and elution, and the type and volume...
Article
Agricultural soils have been analyzed to elucidate whether the trace metal distribution changes in relation to agricultural activities and to predict environmental risk. In addition to the extractability of Cu, Mn, Ni, Pb, and Zn in soils was compared by single extraction (hydrochloric acid (HCl), ethylenediaminetetraacetic acid (EDTA), diethylenet...
Article
The concentrations of Cd, Co, Cr, Cu, Mn, Ni, Pb, Se and Zn in cheese samples packaged in plastic and tin containers were analyzed using inductively coupled plasma-optical emission spectrometry after microwave, wet and dry digestion processes. In order to evaluate the best digestion method, the relationships between the concentrations of trace meta...

In this study, soil samples were collected from Edirne, Turkey in both summer and winter seasons and subjected to the modified Community Bureau of Reference (BCR) sequential extraction procedure in order to investigate the chemical partitioning of metals in soils and to predict heavy metals uptake by wheat grains which grown at the same soils. The...

In this study filamentous fungal biomass-loaded TiO(2) nanoparticles were used for the biosorption of lead(II) ions by flow-injection system coupled to flame atomic absorption spectrometry. The effects of pH, sample volume, loading and elution flow rates, eluent type and volume on the recovery of lead were investigated. Lead ions were sorbed on a b...
