Abstract

NMR 1H and 13C spectroscopy was successfully used to monitor the ozonation of wastewaters generated during the steaming treatment of green lumber of beech wood (Fagus sylvatica). A noticeable diminution of signals from aromatic cycle was observed. An increase of the carbonyl and carboxyl group was also noticed. The signals from the carbohydrates were constant after the ozonation. This study clearly suggest that ozonation is an effective means to degrade the phenolic compounds generated during the steam treatment.

NMR- Spektroskopie ozonisierter Abwässer von dampfbehandelter Buche (Fagus silvatica)

Zusammenfassung

1H und 13C NMR-Spektroskopie wurden erfolgreich eingesetzt, um die Ozonisierung von Abwässern, die während der Dampfbehandlung von waldfrischem Buchenschnittholz (Fagus silvatica) entstehen, zu registrieren. Eine deutlich merkbare Verminderung der Signale aromatischer Ringe wurde beobachtet. Eine Zunahme der Carbonyl- und Carboxyl-Gruppen wurde ebenfalls beobachtet. Die Signale der Kohlenhydrate waren nach der Ozonisierung konstant. Diese Untersuchung weist deutlich darauf hin, dass die Ozonisierung eine wirksame Methode zum Abbau phenolischer Komponenten darstellt, die während der Dampfbehandlung entstehen.
