چکیده
Hydrogen peroxide is an environmentally friendly bleaching chemical that widely used in alkaline media the pulp and paper industry. In this study, unconventional reaction conditions of conventional P-stage were performed to evaluate its effect on cellulose. The objective was “tailor” cellulose degradation according different applications, such as dissolving pulps. Different operating studied: pH variation (alkaline or acidic medium), well addition Cu(II) Cu(II)-phenanthroline complex. hypotheses considered (1) Using H2O2 will favor hemicelluloses removal after depolymerization lead desired degradation, (2) oxidation carried out under ability
