Electrochemical behaviour of sodium dithionite at a platinum electrode and determination of diffusion coefficient in alkaline solution

Anode current on gold in mixed thiosulfate-sulfite electrolytes

“…The conclusion that the rate of sulfite oxidation on gold is limited by the diffusion of sulfite ions agrees with the results of study of an anodic process in this system on graphite [12,13], platinum [14], gold [15,16], and metal oxides [17] electrodes. It is shown in these works that the kinetics of sulfite oxidation has the same diffusion character on different metals.…”

The coordination of imidazole and substituted pyridines by the hemeoctapeptide N-acetyl-ferromicroperoxidase-8 (FeIINAcMP8)

“…Dithionite solutions are unstable towards even trace amounts of dioxygen [34,45,56,57] and towards hydroxide [57], and in aqueous solution the SO°2 radical anion disproportionates [58]. As others have done [43,47,59,60], we have used solid sodium dithionite as the reducing agent in this work.…”

Development of electroconductive polyacrylonitrile fibers through chemical metallization and galvanisation

“…First, the stability of Rongalite and sodium dithionite in solution was investigated. From the literature it is clear that sodium dithionite is relatively unstable over the entire pH range [16][17][18][19][20]. Our experiment, executed at Rongalite decomposed very slowly (with a rate of 0.005 mol l )1 h )1 ).…”
