A kinetic study of the reaction between peroxydisulphate ion and iodine

F. Secco  and  S. Celsi  

Abstract

The kinetics of oxidation of iodine to iodate by peroxydisulphate ion in aqueous solution has been studied by a spectrophotometric technique at 25·0°C and at ionic strength 0·5M. The rate equation, obtained by a statistical treatment, is (i). Catalysis by copper(II) and silver(I) ions and inhibition by oxygen are observed and the effect, –d[I2]/dt=kA[S2O82–]½[I2]½+kB[S2O82–][I2]½(i) of several added salts is also tested. The mechanism is discussed.
