Abstract
The Wet Air Oxidation of four organic complexants was studied. This study focuses on the determination of the main by-products formed and the optimization of the degradation yield in a defined area according to four parameters, which are reaction temperature, initial substrate concentration, reaction time and oxygen partial pressure. This optimization is followed by a classic Doehlert matrix.


Key words: Organic complexants / total organic carbon / Wet Air Oxidation / intermediates -- mineral by-products -- optimization, experimental design.
