【 摘 要 】

The present work establishes and compares the oscillatory behaviour of mono-, di- and trihydroxybenzoic acids as organic substrates in acidic bromate (1.0 mol L-1 H2SO4) without catalyst and in the presence of Mn2+ ion as the main catalyst. The oscillations are also affected by other catalyst such as Fe2+ ion. Further, the oscillations start diminishing in mixed catalyst systems. The experimental parameters were obtained potentiometrically and the results have been interpreted on the basis of FKN mechanism.
