Determination of Sulfide by Cathodic Stripping Voltammetry at a Rotating Silver Disc Electrode.
Abstract
The deposition and stripping behavior of silver sulfide films at the silver rotating disc electrode were investigated. The effect of various factors - rotation rate, scan rate, deposition potential and time, and concentration of sulfide ion - on the stripping peak current and potential were studied. The electrode has been found to be an excellent electrode for cathodic stripping voltammetry for the determination of submicro amount of sulfide ion. Futhermore, differential pulse voltammetry significantly enhanced the signal/noise ratio, and a linear response was obtained over the concentration range (10 to the-8th power - .00001) mol/cu dm of sulfide ion in 0.2 mol/cu dm NaOH.
