Effect of Bleaching Condition on Optical and the Physical Properties During the Bleaching of Poplar Organosolv Pulps with Two-stage Hydrogen Peroxide

Ilhan Deniz and Ahmet Tutus

Abstract: Nine different two-stage bleaching trials were carried out to determine the effect of bleaching conditions on the optical and physical properties of pulps during the bleaching of poplar wood organosolv pulp with hydrogen peroxide. The results indicated that optimum poplar organosolv pulps bleaching conditions were as below; Hydrogen peroxide (H₂O₂) ratio on oven dry (o.d) pulp: 2-4%, alkali (NaOH) charge on o.d pulp: 1.5-3%, Na₂SiO₃ ratio on o.d pulp: 3%, MgSO₄ratio on o.d pulp: 0.5%, EDTA ratio on o.d pulp: 0.5%, reaction temperature: 70°C, reaction time: 70 min and concentration: 16%. Thus, optical and physical properties of bleached poplar organosolv pulps with two-stage H₂O₂were found to be higher than those of unbleached pulps.
