Abstract
The effect of the initial concentration of reactants on the velocity o f chemical fronts in the acid-catalysed chlorite oxidation of tetrathi onate was investigated both numerically and experimentally. Based on a simple two-variable model an expression for front velocity as a funct ion of concentration and diffusion coefficient of reactants was develo ped which can quantitatively describe the observed velocity dependence in slight chlorite excess.
