Abstract

Preconcentration of silver I ions on poly vinylferrocenium /chloride PVF+Cl- modified platinum electrode prior to differential pulse anodic stripping determination of the metal was reported. At the optimum conditions, a calibration curve having two linear parts with different slopes was obtained at the concentration intervals 1x10-3 M – 5x10-5 M and 5x10-6 M – 1x10-8 M. The detection limit was determined as 1x10-9 M. The relative standard deviation was calculated as 9.56 % n = 6 for 1 x 10-6 M Ag+ solution. Interferences of Hg2+, Fe3+ and Pb2+ ions which are capable of forming chloride complexes were examined. The modified electrode was applied to determination of silver ions in spiked water samples.

Özet

G ümüş I iyonlarının poli vinilferrosenyum /klorür PVF+Cl- ile modifiye edilmiş platin elektrotunda önderiştirilmesi ve diferansiyel puls anodik sıyırma voltametrisi ile tayini çalışıldı. Belirlenen optimum koşullarda 1x10-3 M - 5x10-5 M ve 5x10-6 M - 1x10-8 M derişim aralıklarında iki adet doğrusal kısmı bulunan bir kalibrasyon eğrisi elde edildi. Tayin sınırının 1x10-9 M olduğu yöntem için 1x10-6 M Ag+ çözeltisiyle bağıl standart sapma 9.56 % n = 6 olarak hesaplandı. Ayrıca klorür kompleksleri oluşturduğu bilinen Hg2+, Fe3+ ve Pb2+ iyonları için girişim çalışması yapıldı ve modifiye elektrot, gümüş iyonları eklenmiş çeşme suyunda test edildi
