Abstract
This thesis describes a study of the reaction of perox-omonosulphuric acid with some organic substrates, namely methyl orange, methyl red, and the olefinic acids, sorbic acid and 2,4,6-octatrienoic acid. The kinetics of each reaction in aqueous solution were determined over the pH range 2-10 and Activation parameters measured at the rate maximum. Feasible mechanisms and reaction products were suggested. A similar study was made on the reaction of peroxodisulphuric acid with methyl orange and methyl red to determine whether there were any similarities between the reactions of the two peroxoacids with these substrates. All the above work was carried out, where possible, in the absence of buffers by using a pH-stat system as a method of pH control.
