Renjie Dong, in Ecological Engineering, 2013 3.2.2 Re-oxidation of sulphide When the produced sulphide from anoxic zones of CWs is transported to the oxic zones with the presence of available electron acceptors, it may be oxidized back to polysulphides, elemental sulphur, thiosulphate, tetrathion...
A principal reason for the interest in iron aluminides is their potential to resist corrosion in aggressive high-temperature environments. Accordingly, the development programme for this class of alloys has included an investigation of the corrosion properties in mixed oxidant (H2S-H-2-H2O) environment...
The chemical species involved in H2S signaling remain elusive despite the profound and pleiotropic physiological effects elicited by this molecule. The dominant candidate mechanism for sulfide signaling is persulfidation of target proteins. However, the relatively poor reactivity of H2S toward oxidized thio...
Homework Statement One mole of aqueous S2O32- ions reduces four moles of Cl2 molecules. What is the oxidation state of the sulphur containing product of this reaction? Homework Equations The Attempt at a Solution oxidation state in S2O32- = +2 since 4moles of Cl2 are reduced... ...

so that it must be combusted, whereby the hydrogen sulfide and other sulfur compounds, as is the elemental sulfur present in the gas phase, are oxidized to sulfur dioxide. Owing to the large amounts of H2S that are processed, the amounts of SO2that are being emitted in this way are sti...
