摘要
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 S-8. Additionally, a free radical reaction mechanism which describes the formation of elemental sulfur S-8 was proposed.
