The use of peroxymonosulphuric (Ps) acid to remove hexenuronic acid (HexA) present in unbleached eucalyptus kraft pulps was evaluated here. HexA is formed during pulping and is held responsible for reagent consumption during bleaching. Laboratory experiments, using oxygen predelignified eucalyptu...
Because of great environmental pressures, the cellulose industry has studied the potential of use of new bleaching agents among which peroxymonosulfuric acid and peracetic acid stand out. This survey summarizes the results of various laboratory investigations using peracids to delignify eucalyptu...

Environmental implications of the delignification of eucalyptus kraft pulps using peracids
En Chile los recursos de mayor exportación son en el área agroindustrial y de la madera, en donde se produce gran cantidad de residuos. Por un lado en el área agroindustrial,
los frutos secos han tenido un incremento significativo, en especial la nuez de Nogal, generándose una gran cantidad de re...
