Oxidation of manganese (II) with air in water treatment

Manganese is the second most common constituent after iron of impounded wat er and many well waters. It causes difficulties in public supplies and in i ndustrial supplies. In this study, the oxidation of Manganese(II) is studie d in batch reactors in which the concentrations of manganese(IV) was in the range 0-300 mg/L. This study has demonstrated the catalytic effect of MN(I V) on the Mn(II) oxidation by air to the MN(IV) levels of 100 mg/L. A quadr atic equation has been obtained to determine the catalytic reaction rate co nstant, kcat, as a function of Mn(IV).
