Oxyde de fer
Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.

| Résumé : |
Successful decolorisation of real textile wastewater was achieved by means of the advanced Fenton process in conjunction with ultrasound technology. A synergy factor of 6.9 for this combined method was determined. The decolorisation followed zero-order kinetics, and the rate increased with increasing zero-valent iron dose and decreasing pH and hydrogen peroxide concentration. The optimum conditions for an American Dye Manufacturers Institute decolorisation value of 1638 ADMI was found to be a pH of 3.0, an ultrasound frequency of 47 kHz, a zero-valent iron dose of 1.0 g l?1, and a hydrogen peroxide concentration of 1.03 × 10?2 m. Under these conditions, the estimated operating cost to decolorise 96% true colour was estimated to be $US 4.51 m?3. The study demonstrated that the given combined method could be applied to decolorise textile wastewaters. |
