Abstract
AbstractThe decomposition of hydrogen peroxide has been studied in the presence of a large number of metal ions and their complexes1,2). Interest in radiation chemistry of aqueous solutions where hydrogen peroxide is one of the products and the use of acidic ferrous sulphate solutions as dosimeter in these studies has particularly stimulated the investigation on the kinetics of decomposition of hydrogen peroxide in the presence of Fe+2, Fe+3 and their complexes1,2). Ferrous sulphate solution can be used as a dosimeter under acidic conditions only, as at higher pH the hydrolysis of Fe+2 and Fe+3 interferes. Recent studies3‐6) have shown the possibility of using the aqueous solutions of ferro‐ and ferri‐cyanides over a range of pH as dosimeter. In the studies of ferrocyanide and ferricyanide catalysed decomposition of hydrogen peroxide7‐11), it is suggested that the catalytic properties of hexacyano ferrates are through their hydrated products. The present study aims at studying the interaction of aquapentacyanoferrate11) with hydrogen peroxide over a range of pH, concentration and temperature.
