“…During the last three months of the bioreactor operation the average percentage of H 2 S converted into thiosulfate was 0.67 ± 0.11%, mainly due to auto-oxidation of sulfide [ 30 , 41 ] and/or reaction of sulfur with OH − ion in alkaline solution [ 34 , 42 , 43 ]. The highest conversion to thiosulfate was obtained at higher O 2 /H 2 S molar ratios.…”

“…In the presence of excess sulfur (i.e., x > 0), which is the case at oxygen-limited conditions, polysulfide forms [ 42 ]. In this study polysulfide was included in elemental sulfur concentration since S o concentration was calculated by mass balance, taking into account the inlet sulfide and the outlet sulfide, sulfate, and thiosulfate.…”

“…The S released by this breakdown should react' with more hematite and the pyrrhotite to form more pyrite and some oxygen containing anion of S such as S203-2, SO,-", or SO,-2. In any case it seems likely that pH would increase and thus make sulfur more soluble because of its disproportionation to polysulfide and thiosulfate (ARNTSON, DICKSON, and TUNELL, 1960). The polysulfide should then react with the hematite; the net effect is the same in either case, namely destruct,ion of polysulfide, depositiol~ of covellite and acanthite.…”
