abstract
The formation of sulfur-containing compounds occur in a number of areas such as well water, lakes, oil fields, anaerobic sewage, and industrial waste water. The oxidation of sulfur-containing compounds was studied with ferrate(V) (Fe(V)) using pre-mix pulse radiolysis technique. The rates decreased with increasing pH. The pH dependence was related to higher reactivity of protonated Fe(V) than of deprotonated Fe(V) ion. Fe(V) reacted nearly three orders of magnitude faster with sulfur-containing compounds than Fe(VI). The oxidation by Fe(VI) could be enhanced in the presence of appropriate one-electron-reducing agents. Original is an abstract.
