The Kinetics and Mechanism of the Oxidation of Inorganic Oxysulfur Compounds by Potassium Ferrate Part III - Trithionate and Pentathionate Ions

Potassium ferrate (K2FeO4) is an effective, selective oxidizing agent, giving an environmentally benign product of Fe(II) or Fe(III). The present study completes the experimental investigation of the oxidation of the inorganic oxysulfur compounds. The kinetics and mechanism of the ferrate oxidation have been determined for the sulfite (SO23 ) [1 3], thiosulfate (S2O 3 ) [3, 4], dithionite (S2O 4 ) [3], disulfite (S2O 5 ) [3], dithionate (S2O 6 ) [5] and Inorganic Reaction Mechanisims, Vol. 5, pp. 281-304 © 2005 Old City Publishing, Inc.
