RESEARCH ON RELEASE OF LIGNIN IN PEROXIDE BLEACHING OF WASTE AT ALKALINE CONDITIONS
The release of the dissolved and colloidal substances (DCS) from deinked pulp in the peroxide bleaching under alkaline conditions was studied. The effects of NaOH dosage, H2O2 dosage and reaction temperature on cationic demand and the release of lignin were discussed. The results showed that the increase of NaOH dosage, H2O2 dosage and reaction temperature resulted in the improvement of cationic demand and the content of lignin. Furthermore, NaOH exhibited more significant effect on the release of lignin than H2O2.
