Abstract

The aim of this study is to investigate the contents of essential and toxic trace element by the energy-dispersive X-ray fluorescence spectrometry (EDXRF) in seaweed (Ulva lactuca) from collected eight different regions of Istanbul (Turkey) in the years of 2006 and 2007. It has been analyzed by the samples using two annular radioactive sources and an Ultra-LEGe detector. A radioisotope excited X-ray fluorescence analysis using the method of multiple standard additions was applied for the elemental analysis of seaweed samples. In this study, the metal concentrations in the seaweed samples vary within 0.8- 1.8% and 1.1-2.1% for Cl, 0.6-2.3% and 0.2-3.4% for K, 0.9-2.7% and 0.4-2.7% for Ca, 0.2-1.0% and 0.2-0.3% for Ti, 0.7- 2.1% and 0.7-2.3% for Fe, 0.05-0.1% and 0.04-0.1% for Br, 0.3-0.6% and 0.3-0.4% for Sr, 0.1-0.2% and 0.1-0.2% for I, and 0.09-0.3% and 0.09-0.1% for Ba in the years of 2006 and 2007, respectively. The results demonstrated that these seaweeds contain some essential element, but no toxic element.

Özet

Bu çalışmanın amacı, 2006 ve 2007 yıllarında İstanbul’un sekiz farklı bölgesinden toplanan deniz yosunlarında, EDXRF (enerji ayrımlı X-ışını floresans spektrometresi) tekniği kullanılarak temel ve toksit bazı elementlerin miktarlarının belirlenmesidir. Numuneler iki adet radyoaktif kaynak ve Ultra-LEGe tipi bir detektör ile analiz edilmiştir. Deniz yosunlarının element konsantrasyonun belirlemede, radyoaktif uyarımlı x-ışını floresans analizlerinde kullanılan çoklu standart ilave metodu kullanılmıştır. Çalışmada deniz yosunu örneklerindeki metal konsantrasyonunun 2006 ve 2007 yılları için sırasıyla; Cl için %0,8-1,8 ve %1,1-2,1 K için %0,6-2,3 ve %0,2-3,4, Ca için %0,9-2,7 ve %0,4-2,7, Ti için %0,2-1,0 ve %0,2-0,3, Fe için %0,7-2,1 ve %0,7-2,3, Br için %0,05-0,1 ve %0,04-0,1, Sr için %0,3-0,6 ve %0,3-0,4, I için %0,1-0,2 ve %0,1-0,2, ve Ba için %0,09-0,3 ve %0,09-0,1 aralığında değiştiği gözlenmiştir. Sonuçlara bakıldığında deniz yosunu örneklerinde toksik içerikli elementlere rastlanmamıştır.
