A sensitive voltammetric method has been developed for the determination of total or single
species of sulfur anions containing sulfide, sulfite and thiosulfate. The method is based on
the catalytic effect of tris (2, 2'-bipyridyl) Ruthenium (II)(Ru (bpy) 2+ 2) as a homogeneous
mediator on the oxidation of those anions at the surface of a glassy carbon electrode. A
reversible redox couple of Ru (II)/Ru (III) were observed as a solute in aqueous solution.
Cyclic voltammetry study showed that the catalytic current of the system depends on the ...
