Hirfanlı baraj gölünde eser elementlerin ICP-OES ile tayini

Bu çalışmada, Kızılırmak üzerine kurulmuş olan Hirfanlı Baraj Gölü`nde eser elementlerin tayin için ICP-OES kullanıldı. Hirfanlı Baraj Gölü`nün değişik yerlerinden polietilen şişelere bir iki mililitre HCl eklenerek su örnekleri alındı. Bu örneklerdeki eser elementler, Perkin Elmer marka ICP-OES cihazıyla tayin edildi. ICP-OES cihazıyla, barajdan gelen su örneklerindeki demir, bakır, kurşun, krom, çinko, molibden ve selenyum elementleri tayin edildi. Uygun standart çözeltilerle belirli dalga boylarında elementlerin kalibrasyon işlemi yapıldı. Cihaz önce sertifikalı örnekteki elementlerin ölçümleri yapılarak duyarlılığı tespit edildi. Daha sonra su örneklerindeki elementlerin analizleri yapıldı. Baraj gölünde yapılan ölçümlere göre; Fe (III) 40 ± 0,3 µg/L, Cu (II) 10 ± 0,1 µg/L, Pb (II) 25 ± 0,1 µg/L, Cr (III) 15 ± 0,2 µg/L, Zn (II) 22 ± 0,2 µg/L, Mo (VI) 8 ± 0,1 µg/L, Se (IV) 35 ± 0,3 µg/L olarak % 95 güven aralığı ve 4 ölçümün sonunda bulunmuştur.
