Kinetics of Permanganate Consumption by Natural Oxidant Demand in Aquifer Solids
Effectiveness of permanganate (MnO4-) injection for in situ chemical oxidation is often controlled by the natural oxidant demand (NOD) of the aquifer solids. In this work, a simple procedure was developed and applied to generate a database of NOD kinetic parameters for six different models for 50 different aquifer materials. Representing oxidant consumption as an initial instantaneous reaction with a portion of the total NOD and as a second order reaction between MnO4- and the remainder of the NOD provided a good match with experimental results from batch studies, without imposing an unnecessary ...
