Gümüş farklı alanlarda yaygın olarak kullanılmaktadır ve yüksek konsantrasyonlarda toksiktir. Bu çalışmada gümüş(I) iyonlarına seçici yeni bir PVC membran potansiyometrik elektrot geliştirildi. Yeni geliştirilen elektrot, 1,0×10-5–1,0×10-1 M konsantrasyon aralığında 53,0±3,6 mV/on katlık derişim yakın-Nernstian tepkiye ve 4,2×10-6 M’lık düşük bir tayin limitine sahiptir. Elektrot, 10 saniyeden kısa hızlı cevap zamanına sahiptir ve pH 3,0–8,0 aralığında pH değişikliklerinden etkilenmeden çalışabilmektedir. Son olarak önerilen yeni elektrot, su numunelerindeki gümüş(I) iyonlarını yüksek geri kazanımlarla tespit edebilmektedir.
