Degradation experiments in controlled conditions

With the aim of improving the ozonation method, IMIDA have carried out more experiments at laboratory scale in controlled conditions.

Ozone tests were developed in a glass container (volume 150 L) connected to the small-scale ozone generator. All assays were carried out using a pyrex glass vessels (110 mm long, 80 mm diameter) containing 100 g of two different soils spiked with a mixture of pesticides.

Ozonation treatment was applied to both soils at a fixed ozone concentration. A control experiment was also conducted using soil not exposed to ozonation.
