II ÖZET Bu çalışmada, Ener j i-Dağılımlı X-ışını Floresansı (EDXRF) metodu, misket elması, sarı elma ve kura elması türlerinin kalitatif ve kantitatif analizi yapıldı. Kalitatif analizde elmalarda, bazıları eser miktarda olmak üzere, Ag, K, Ca, Fe, Al, Sc, Cu, Kr, Mh, Co, ve Rb elementlerinin bulunduğu gözlendi. Elma örneklerinin analizinde en iyi metodun, numunelerin 700°C ta yakıldıktan sonra analizi olduğu belirlendi. Elmalarda, K'un en yüksek konsantrasyonda bulunduğu, ikinci bollukta ise Ca olduğu belirlendi. Bu elementler bakamından en zengin elma türünün misket olduğu ve yakma sonucu kalan misket elması örneklerinde (-0.04 gr) X konsantrasyonunun %71.666 ± 5.662 olduğu saptandı.
ABSTRACT In this study, samples of various apple species (Misket, Golden, Kum Elmasa) ' has been analyzed qualitatively and quantitatively by EDXRF method. In qualitative analysis, presence of Ag, K, Ca, Fe, Al, Sc, Cu, Kr, Mn, Co and Rb elements (most in trace amount) was observed. Best analysical technique was found to be burning the samples in furnace at 700°C before analysis. The highest elemental concentration in the samples left after burning (~0.04 gr) was found to be in Misket species apples, and for K with a value of %71.766 ± 5.662. Second highest concentration found was that of Ca.
