Comparative study of stone-ground wood pulp and native wood 3. Application of fluorescence spectroscopy to a study of the weathering of stone-ground pulp and native wood

Laccase mediated oxidation of industrial lignins: Is oxygen limiting?

“…In previous studies the modification of biphenyl groups were shown to affect the fluorescence properties of the lignin [19]. Similarly, Nugroho Prasetyo et al [7] also followed the changes in fluorescence and correlated these changes with changes at molecular level observed with NMR, GC-MS and SEC chromatograms.…”

Degradation of Lignin Derivatives by Photocatalysts

“…Fluorescence spectroscopy was used as a means to identify non-aliphatic component in the complex mixture of lignin degradation products. Fluorescence emission in lignin is attributed to aromatic structures such as conjugated carbonyl, biphenyl, phenylcoumarone, and stilbene groups [39,40]. New fluorophores were detected in the time ranging from 10 min to around 40 min ( Figure 14 Comparing pathway (2) and pathway (3) from Figure 15, it was observed that the fluorophores produced had similar retention times and similar peak areas.…”

Photocatalytic Active Coatings for Lignin Degradation in a Continuous Packed Bed Reactor

“…Fluorescence spectroscopy was used as a means to identify nonaliphatic component in the complex mixture of lignin degradation products. Fluorescence emission in lignin is attributed to aromatic structures such as conjugated carbonyl, biphenyl, phenylcoumarone, and stilbene groups [38,39]. New fluorophores were detected in the time ranging from 10 min to around 40 min ( Figure 12) with application of TiOSO 4 30.6 wt% catalyst.…”
