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%, MgSO4 ratio 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 H2O2 were found to be higher than those of unbleached pulps.
