Peroxynitrite mediated delignification of pulp: A comparative study on the bleaching properties of the carbonate and hydroxyl radicals
2004 (English)In: Journal of wood chemistry and technology, ISSN 0277-3813, E-ISSN 1532-2319, Vol. 24, no 2, 83-98 p.Article in journal (Refereed) Published
Oxygen delignified pulps were bleached with hydroxyl and carbonate radicals produced from peroxynitrite. The carbonate radical treated pulps showed better selectivity and an increase in brightness. For both radicals, good kappa reductions were obtained. This study shows that the carbonate radical anion is a possible green oxidant for future delignification technologies.
