Oxalic acid formation during ECF and TCF bleaching of kraft pulp
1997 (English)In: Proceedings Minimum Effluent Mills Symposium, 1997, 63-66 p.Conference paper (Refereed)
The formation of oxalic acid (I) during bleaching of softwood kraft pulp was studied. Bleaching agents used were O, H2O2, ClO2, peracetic acid (II), and O3. The formation of I acid increased linearly with the decrease in kappa no. II bleaching gave less I than the other bleaching agents. In O3 bleaching ∼1/3 of the formed I was adsorbed on the pulp and not released until a later stage.
