“…This extraction method is based on transferring analytes from the aqueous phase to the solid phase. Different solid phases have been used as sorbent for the separation and preconcentration of copper or iron, including multi-walled carbon nanotubes [11], hybrid amine-functionalized titania/silica nanoparticles [12], C18 cartridge [13], polyurethane foam [14], Schiff basemodified duolite XAD 761 [15], Dowex Optipore L-493 resin [16], Schiff base-modified Amberlite XAD-4 [17], etc.…”

In the present study, a new solid phase extraction method was developed for simultaneous preconcentration of copper(II) and iron(III) ions from natural waters. The analytes were first complexed with 4aminoantipyrine at pH 8.0 and then passed through the column packed with C18-silica. The retained analytes on the C18-silica were eluted with 1.0 mL of 0.5 M nitric acid in 10% ethanol and determined using flame atomic absorption spectrometer. The influence of several variables such as sample pH, ligand amount, eluent type, sample and eluent flow rates, and sample volume on the retention/or elution of the analytes were examined and optimized. The effects of some interfering ions on the retentions of analytes on C18-silica were also enquired. The detection limits were 0.89 µg/L for Cu and 1.41 µg/L for Fe with a preconcentration factor of 20. The calibration graphs were linear in the concentration range of 5.0-125 µg/L of the analytes. The calibration equations were A=2.36x10 -3 C + 4.55x10 -4 for Cu and A=1.45x10 -3 C + 8.88x10 -4 for Fe. The accuracy of the proposed method was verified by the analysis of SPS-SW2 Batch 127 certified reference water. The method was applied to river water and seawater samples with recoveries in the range of 95-99%. Anahtar Kelimeler: copper, iron, preconcentration, solid phase extraction C18-silika dolgulu mini kolon kullanılarak doğal sulardan Bakır(II) ve Demir(III) iyonlarının önderiştirilmesi ve alevli AAS ile tayini ÖZ Bu çalışmada, doğal su örneklerinden bakır(II) ve demir(III) iyonlarının aynı anda önderiştirilmesi için yeni bir katı faz ekstraksiyon yöntemi geliştirilmiştir. Analitler 4-aminoantipirin ile pH 8.0'de kompleksleştirilmiş ve C18-silika ile paketlenmiş mini kolondan geçirilmiştir. Kolonda alıkonunan analitler %10 etanolde hazırlanmış 1 mL 0,5 M nitrik asit çözeltisi ile elüe edilmiş ve alevli atomik absorpsiyon spektrometresi ile tayin edilmiştir. Örnek pH'sı, ligand miktarı, elüent türü, örnek ve elüent akış hızları ve örnek hacmi gibi çeşitli değişkenlerin analitlerin alıkonması veya elüsyonu üzerine etkisi incelenmiş ve optimize edilmiştir. Ayrıca analitlerin C18-silika kolonunda alıkonmasına bazı yabancı iyonların etkileri incelenmiştir. Gözlenebilme sınırları 20 kat önderiştirme faktörü ile Cu için 0,89 µg/L ve Fe için 1,41 µg/L olarak belirlenmiştir. Kalibrasyon grafikleri 5,0-125 µg/L bakır(II) ve demir(III) derişimi aralığında doğrusaldır. Kalibrasyon eşitlikleri Cu için A=2,36x10 -3 C + 4,55x10 -4 ve Fe için A=1,45x10 -3 C + 8,88x10 -4 olarak belirlenmiştir. Önerilen yöntemin doğruluğu sertifikalı referans su örneğinin (SPS-SW2 Batch 127) analizi ile doğrulanmıştır. Geliştirilen yöntem nehir suyu ve deniz suyu örneklerine % 95-99 arasındaki geri kazanım değerleri ile başarılı bir şekilde uygulanmıştır.

A crown-ether-type colorimetric chemosensor EDDAJ (9,9 0 -((1E,11E)-5,8-dioxa-2,11-diazadodeca-1,11-diene-1,12-diyl)bis (2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-8-ol) was synthesized. EDDAJ could detect Fe 3+/2+ by a color variation from colorless to dark green in aqueous media. Detection limit of iron ion was 0.43 μM. Complexation ratio of EDDAJ to Fe 3+ was determined to be 1:1 with the results of Job plot and ESI-mass. Based on Job plot, EPR, and ESI-mass experiments, the probing mechanism of EDDAJ to Fe 3+/2+ was demonstrated.
