Abstract The Bureau of Mines performed chemical research to elaborate details of sulfur chemistry pertaining to the citrate flue gas desulfurization process in which sulfur dioxide (SO2), absorbed (as bisulfite ion) in a buffered sodium citrate solution, is reduced by hydrogen sulfide (H2S) according to the overall reaction 2H2S + HSO3(-1) + H (+1) yields 3S + 3H2O. The rate-limiting step in the process was shown to be the reduction by H2S of thiosulfate S2O3(-2) that is formed as an intermediate.
