Polysulfide Concentration and Chain Length in the Biological Desulfurization Process: Effect of Biomass Concentration and the Sulfide Loading Rate.

ABSTRACT: Removal of hydrogen sulfide (H₂S) can be achieved using the sustainable biological desulfurization process, where H₂S is converted to elemental sulfur using sulfide-oxidizing bacteria (SOB). A dual-bioreactor process was recently developed where an anaerobic (sulfidic) bioreactor was used between the absorber column and micro-oxic bioreactor. In the absorber column and sulfidic bioreactor, polysulfides (S_x^2-) are formed due to the chemical equilibrium between H₂S and sulfur (S₈). S_x^2- is thought to be the intermediate for SOB to produce sulfur via H₂S oxidation. In this study, we quantify S_x^2-, determine their chain-length distribution under high H
