Detection of sulfite via the trapping and subsequent electrochemical detection of hydrogen sulfide

Abstract:

The electrochemical oxidation of N,N-diethylphenylene-1,4-diamine (DEPD) and its subsequent reaction with sulfide has been exploited as a means of quantifying the latter. Re-oxidation of the resulting adduct was found to lead to an increase in the oxidative current which scaled linearly with sulfide concentration over the range 30 μM to 516 μM, although it was found that the upper limit could be extended through simply increasing the concentration of the DEPD indicator. As such the detection ...
