The effect of oxidation with single electron oxidants compared to a laccase treatment of TMP wood fibres

摘要

Previous work has shown that laccase is able to catalyse auto adhesion of lignin rich wood pulp. This promises the replacement of environmentally hazardous glue in composites with a laccase treatment of the pulp. In the present work we compare spectroscopic results of this treatment with those of other better defined oxidative treatments to examine the origin of this auto adhesion. The results of the laccase treatment is also achieved by laccase-ABTS or -HBT treatment. This points to the fact that the auto adhesion depends on general features of solid state lignin oxidation.
