Information About Author:

A method is described for the determination of suifide-ions by cathodic stripping voltammetry at mercury film electrode in 1 M NaOH. The peak height observed at –0,76 ± 0,96 V (saturated silver – chloride electrode) was proportional to the concentration of suifide-ions between 2·10-6 and 1·10-4 M. Tiosulfate - ions do not prevent the determination of sulfide – ions
