    Determination of Potassium, Calcium and Chlorine in Some Vegetables by EDXRF
    (Pergamon-Elsevier Science Ltd, 2006) Doğan, O.; Tıraşoğlu, Engin
    Total concentration of potassium, calcium and chlorine was determined in the presence of each other and irrespective of the nature of their compounds, in the leaves of Urticae dioico L. and Spinacia oleracea L. (spinach) plants by EDXRF. The enhancement of potassium K X-rays due to calcium K X-rays and enhancement of chlorine K X-rays due to potassium and calcium K X-rays present in the samples were avoided by selective secondary excitation method of the samples. Our, results were compared with other experimental results.

    Elemental Analysis of Trace Elements in Fly Ash Sample of Yatağan Thermal Power Plants Using EDXRF
    (Pergamon-Elsevier Science Ltd, 2006) Doğan, O.; Kobya, M.
    Fly ash samples collected by means of an electrostatic precipitator from the lignite-fired Yatagan Power Plants of the located in Turkey was analysed using X-ray fluorescence technique. Five trace elements, namely Nd, Ba, Sr, Mo and As were quantified using XRF. These concentration values can be helpful in developing a environmental pollution abatement approach for various applications of fly ash such as cement manufacture, wastewater treatment, lightweight contraction aggregate, ceramic production, and secondary source in recovery of valuable elements. Present results compared with results of the Kemerkoy thermal power plants [Sahin Y, Karabulut A, Budak G. A practical method for the analysis of overlepped peaks in energy dispersive X-ray spectra. Appl Spectrose Rev 1996;31:333-45].
