Özet
Bu çalı?mada çözelti ortamında bulunan Pb(II) iyonları modifiye Amberlite XAD-16 içeren mini kolon kullanılarak zenginle?tirildi ve alevli atomik absorpsiyon spektrometrik yöntem ile tayin edildi. pH, geri alma çözeltisinin türü, deri?imi, hacmi ve akı? hızı, örnek çözeltisinin hacmi ve akı? hızı, sorpsiyon kapasitesi gibi bazı faktörlerin zenginle?tirme verimine etkisi ara?tırıldı. Deneysel olarak belirlenen en uygun ?artlarda Pb(II) iyonunun geri kazanma verimi sırasıyla % 100,3 ± 0,49 olarak elde edildi (N=5). Yöntemin gerçek numunelere uygulanabilirliğini ara?tırmak için Na+ , K+ , Mg 2+, Clve NO3 - gibi bazı iyonların geri kazanma verimine etkisi incelendi. Önerilen yöntem, Dicle nehir suyu gibi gerçek örneklere Pb(II) iyonlarının tayini için uygulandı. Dicle nehri suyuna uygulanan yöntemde Pb(II) iyonu tayini için geri kazanma verimi % 32,4 ± 0,549 olarak elde edildi. Ayrıca önerilen yöntemin doğruluğu, standart referans madde analiz edilerek kontrol edildi. Anahtar Kelimeler: Pb(II) iyonları, Katı Faz Ekstraksiyonu (SPE), Alev Atomik Absorpsiyon Spektroskopisi (FAAS), Zenginle?tirme, Geri Kazanım
In the present study, Pb(II) ions present in aqueous medium were enriched by a mini column containing modified Amberlite XAD-16 and determined by Flame Atomic Absorption Spectroscopy (FAAS). Influences of some factors, such as pH, type, concentration, and volume and flow rate of recovery solution, sorption capacity on enrichment yield were investigated. In the optimum conditions, recovery yield of Pb(II) ions was found to be 100,3±0,49% (N = 5). In order to investigate applicability of the method to the real samples, effects of several ions, such as Na+ , K+ , Mg2+, Cland NO3 on recovery yield were studied. The proposed method was applied to real samples, such as Tigris River water, for determination of Pb(II) ions and the recovery yield was found as 32,4±0,549 % (N = 5). Furthermore, accuracy of the method was checked by analyzing with the standard reference material. Keywords: Pb(II) ions, Solid Phase Extraction (SPE), Flame Atomic Absorption Spectroscopy (FAAS), Enrichment, Recovery
