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.Keywords: analytical chemistry, ion selective electrode, preparation, silver wire, potentiometric measurements, sulphide ionsPublished in DKUM: 17.08.2017; Views: 1403; Downloads: 128 Full text (80,69 KB)This document has many files!
