Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N° 22 (Novembre 2009) . - pp. 9902–9909 Titre : Wet oxidation of thiocyanate under different pH conditions : kinetics and mechanistic analysis Type de document : texte imprimé Auteurs : Sergio Collado, Auteur ; Adriana Laca, Auteur ; Mario Díaz, Auteur Année de publication : 2010 Article en page(s) : pp. 9902–9909 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Thiocyanate Wet oxidation Résumé : The wet oxidation of thiocyanate has been investigated in a 1-L semibatch reactor at temperatures in the range of 438.15−468.15 K and total pressures between 2.0 × 103 kPa and 8.1 × 103 kPa. The initial pH value of the reaction media was varied between pH 2 and pH 12 and was found to be a key parameter in the rate of thiocyanate degradation. The evolution of concentration of substrate and products (sulfate and ammonium) were analyzed. Based on the experimental data and bibliography information, a kinetic model was obtained and, here, possible pathways, depending on the initial pH of the media, are suggested for thiocyanate oxidation.
