Assessment of the experimental conditions affecting natural oxidant demand of soil by permanganate

This study provides a broader perspective of the issues and concerns related to determining the permanganate natural oxidant demand of soil while evaluating the effects that initial oxidant concentration, soil to water ratio, and mixing have on the rate and extent of permanganate consumption. It was found that mixing conditions significantly influenced the kinetic expression of permanganate natural oxidant demand while soil to water ratios were not shown to have a significant effect as long as initial permanganate concentrations were sufficient to overcome the oxidant demand of the soil (i.e., were not limiting).
