4. Laboratory-scale experimentation

Laboratory-scale experimentation is designed first and foremost to select the oxidant and quantify the doses of reagents required, thus providing the first essential elements for sizing. On this scale, if possible, the oxidant consumption by the NOD water or soil matrix can also be evaluated. Finally, we can measure various parameters under controlled conditions, such as pH or temperature variations, or even quantify the release of metals if the soil is highly polluted with metals.

4.1 Evaluation of oxidizer efficiency

For a given pollution situation, one or more oxidants are chosen according to the pollutant's reactivity. The preceding paragraph gives an initial overview of the correspondences between pollutants and common oxidants. If necessary, additional...
