Título: | The role of bound chlorine in the brightness reversion of bleached hardwood kraft pulp |
Autor(es): | Eiras, Kátia Maria Morais Colodette, Jorge Luiz Silva, Vanessa Lopes |
Abstract: | Our previous paper showed fragmentary evidence that pulp brightness reversion may be negatively affected by its organically bound chlorine (OX) content. A thorough investigation on eucalyptus kraft pulp led to the conclusion that OX increases reversion of certain pulps but this trend is not universal. Alkaline bleaching stages decrease reversion regardless of pulp OX content. Pulps bleached with high temperature chlorine dioxide revert less than those bleached with conventional chlorine dioxide in sequences ending with a chlorine dioxide stage but similarly in sequences ending with a final peroxide stage. The use of secondary condensate for pulp washing decreases reversion. |
