Abstract
The preparation and usability of a sulphide ion selective electrode, prepar ed by means of chemical pretreatment of silver wire with an ammonium perdis ulphate solution, and the sulphidization in an alkaline sulphide solution a re 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 prep aration of the described electrode.
