Complete reduction of polychlorinated biphenyls by acid - etched steel wool in supercritical carbon dioxide / Yun-Chieh Chen in Industrial & engineering chemistry research, Vol. 51 N° 19 (Mai 2012)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 19 (Mai 2012) . - pp. 6625-6630 Titre : Complete reduction of polychlorinated biphenyls by acid - etched steel wool in supercritical carbon dioxide Type de document : texte imprimé Auteurs : Yun-Chieh Chen, Auteur ; Weisheng Liao, Auteur ; Hwa-Kwang Yak, Auteur Année de publication : 2012 Article en page(s) : pp. 6625-6630 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Supercritical state Carbon dioxide Steel Résumé : Inexpensive household steel wool was used as a reducing agent for the reductive dechlorination of polychlorinated biphenyls (PCBs) in supercritical carbon dioxide (scCO2). Untreated steel wool does not produce significant results. Steel wool treated with 6 N HCl, however, showed complete reduction of the PCBs (Aroclor 1254) used. Scanning electron microscopy (SEM) reveals the formation of nanoscale pits (nanopits) on the surface of steel wool after etching with HCl. These nanopits are responsible for the high efficiency of the hydrodechlorination process.
