Abstract

In this study, Na+ -selective potentiometric PVC-membrane electrode was developed with the commercially purchased ionophore substance to be used to determine sodium concentration in water samples. The potentiometric performance characteristics of the electrode were determined and its suitability for environmental analysis was investigated. For the measurements taken with the Na+ -selective electrode, a potential difference of 50,8 (±1,4) mV/pNa was observed for each 10 fold concentration change against the main ion solution The electrode was determined to exhibit a linear behavior towards the main ion solution in the concentration range of 1x10-1 -1x10-5 mol L-1 and was highly selective towards the tested ions. Micro dead volume flow cells were prepared in the laboratory and the sodium ion determination was made directly in environmental water samples by using these electrodes developed as a detector in the flow injection analysis system. In addition, sodium ion determination in water samples was made using the assay method developed using the standard addition method and all measurements were given in comparison with potentiometric results. The results show that the Na+ -selective micro-potentiometric PVC-membrane electrode can effectively be used for routine determination of sodium ion in environmental samples.

Özet

Bu çalışmada, su numunelerindeki sodyum derişiminin belirlenmesinde kullanılmak üzere ticari olarak satın alınan iyonofor madde ile Na+ -seçici mikro potansiyometrik PVC-membran elektrot geliştirildi. Elektrotun potansiyometrik performans karakteristikleri belirlendi ve çevresel analizlere uygunluğu araştırıldı. Hazırlanan Na+ -seçici elektrot ile alınan ölçümlerde ana iyon çözeltilerinin derişimindeki her 10 katlık değişimine karşılık gelen potansiyel farkı 50,8 (±1,4) mV/pNa olarak gözlendi. Elektrot, 1x10-1 -1x10-5 mol L-1 derişim aralığında ana iyon çözeltisine karşı doğrusal davranış sergilediği ve test edilen iyonlara karşı oldukça seçici olduğu belirlendi. Laboratuvarda mikro ölü hacme sahip akış hücreleri hazırlandı ve akış enjeksiyon analizi sisteminde geliştirilen bu elektrotların detektör olarak kullanılması ile çevresel su numunelerinde sodyum iyonu tayini doğrudan yapıldı. Ayrıca, su numunelerindeki sodyum iyonu tayini standart ekleme yöntemi kullanarak geliştirilen tayin yöntemi ile de yapıldı ve tüm ölçümler potansiyometrik sonuçlarla karşılaştırmalı olarak verildi. Elde edilen sonuçlar, geliştirilen Na+ -seçici mikro potansiyometrik PVC-membran elektrot ile çevre numunelerindeki sularda sodyum iyonunun rutin tayininde etkin bir şekilde kullanılabileceğini göstermektedir.
