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...
