Production of paper grade pulp is still relying on the use of chlorine dioxide in ECF bleaching sequences in spite of the AOX pollutants this process releases in the environment and in paper products. The shift towards the use of TCF bleaching sequences will be necessary and is already made possible by the total substitution of chlorine dioxide for ozone, a greener and more powerful oxidant. It is shown in this thesis that an ozone TCF bleached pulp can reach brightness and strength properties equivalent to that of a conventional ECF pulp. Furthermore, a UV resonance Raman spectroscopy study demonstrates the superiority of ozone (associated with hydrogen peroxide) in stabilising the brightness, compared to the joint use of chlorine dioxide ...
