DIFFERENT PRETREATMENTS EFFECTIVENESS IN PEROXIDE BRIGHTENING OF HIGH YIELD PULPS

DIFFERENT PRETREATMENTS EFFECTIVENESS IN PEROXIDE BRIGHTENING OF HIGH YIELD PULPS

The objective of this work is to evaluate the behavior of different commercial metallic ion chelants used as pretreatment in hydrogen peroxide bleaching of an industrial cold soda chemimechanical pulp of hardwoods. Pretreatment trials were made with four chelants (A: DTPA, B: DTPMPA; C: HEDTA, D: hy...
