Abstract
Method for determining total organic sulfur using reductive pyrolysis and specific electrochemical detection of sulfide ion at a mercury electrode. The method is especially useful for the determination of sulfur in matrices containing halogen or nitrogen compounds. Under routine conditions, a detection limit of less than 50 parts per billion (ppb) can be achieved using differential pulse cathodic stripping voltammetry as the detection mode.
