Ambashta, Auteur ; Eveliina Repo, Auteur ; Mika Sillanpaa, Auteur Année de publication : 2011 Article en page(s) : pp. 11771-11777 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Magnetic  field Résumé : A novel method for the degradation of tributyl phosphate was investigated through the use of nanopowders of iron and iron-nickel. A combination of magnetic field and sonication was used to induce degradation. Using a tributyl phosphate concentration of 300 ppm at pH 4, the Fenton reaction was initiated in the presence of sonication and a reduction in organic carbon content of up to 50% could be created under an induced magnetic field of 0.7 T. The magnetic properties of powders after sonication treatment, in the presence and absence of a magnetic field, were observed to be different. Different degradation mechanisms were proposed under the influence of varying induced magnetic field for iron and iron-nickel.
