Abstract

Opisujemi pripravo sulfidne ionoselektivne elektrode s kemijsko obdelavo srebrne žice v amonijevem peroksodisulfatu in alkalni sulfidni raztopini. Elektroda omogoča direktne potenciometrične meritve koncentracij sulfidnih ionov v alkalnih raztopinah navzdol do ▫$10^{-6} mol/L$▫. Priprava elektrode je enostavna in hitra

Secondary title: Priprava elektrode srebro/srebrov sulfid s kemično obdelavo srebrne žice
Secondary abstract: The preparation and usability of a sulphide ion selective electrode, prepared by means of chemical pretreatment of silver wire with an ammonium perdisulphate solution, and the sulphidization in an alkaline sulphide solution are described. The electrode is suitable for direct potentiometric measuring of sulphide in alkaline solutions of concentrations down to ▫$1 X 10^{-6} mol/L$▫. The 45 min required for each chemical treatment are enough for the preparation of the described electrode.
