Abstract

The amount of arsenic (As) in the earth increases every day and adversely affects the life of all living beings, including human health. Therefore, studies on the development of As determination methods are gradually gaining importance. The foundation of the Diffusive Gradients in Thin Film (DGT) technique addressed in this study is based on the diffusion process. The analyte to be determined passes through different layers in the DGT unit and reaches the adsorber gel layer. In the study presented, the gel obtained from iron (III) oxide (Fe2O3) was used as the adsorber layer. The use of the DGT technique in the amount determination of As(III) and As(V) species in the aqueous medium was examined and all the measurements performed during the experimental studies were observed to be made with an ICP-MS device. Different parameters were evaluated in terms of different pH values, ionic strength effects, gel layer thickness and the effects of the eluent materials and the most suitable working conditions were determined.

Difüzyon Yöntemi (Diffusive Gradients in Thin Film; DGT) Kullanılarak Farklı Arsenik Türlerinin Adsorpsiyon Çalışmalarının Araştırılması

Abstract

Yeryüzünde bulunan arsenik (As) miktarı günden güne artış göstererek insan sağlığı da dahil olmak üzere tüm canlı hayatını olumsuz yönde etkilemektedir. Bu nedenle As tayin yöntemlerinin geliştirilmesine yönelik çalışmalar her geçen gün önem kazanarak artmaktadır. Bu çalışmada yer alan Diffusive Gradients in Thin Film (DGT) yönteminin temeli difüzyon işlemine dayanmaktadır. Tayin edilmek istenilen analit, DGT ünitesinin içerisinde bulunan farklı katmanlardan geçerek adsorplayıcı jel tabakasına ulaşmaktadır. Sunulan çalışmada adsorplayıcı tabaka olarak demir (III) oksit (Fe2O3)’den elde edilen jel kullanılmıştır. DGT yönteminin sulu ortamda As(III) ve As(V) türlerinin miktar tayininde kullanımı incelenmiş deneysel çalışmalar sırasında gerçekleştirilen tüm ölçüm işlemleri, ICP-MS cihazı ile gerçekleştirilmiştir. Farklı pH değerleri, farklı derişimde iyonik şiddet etkileri, jel tabakası kalınlığı ve kullanılan eluent maddelerin etkileri bakımından farklı parametreler değerlendirilmiş, en uygun çalışma koşulları belirlendi.
