Mechanism for the Formation of Elemental Sulfur from Modified Stretford Process
In this paper, the mechanism for the formation of elemental sulfur from the modified Stretford process was investigated using cyclic voltammetry (CV). The results showed that hydrosulfide (HS-) is first oxidized to produce polysulfide ion (Sx2-) which is reactive intermediate product and will further transform to form elemental sulfur S8. Additionally, a free radical reaction mechanism which describes the formation of elemental sulfur S8 was proposed.
