Mechanism for the Formation of Elemental Sulfur from Modified Stretford Process

Abstract:

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 (S_x^2-) 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.
