Structural analysis of photodegraded wood by means of FTIR spectroscopy

摘要: We report on the detailed analysis of chemical modifications and structural changes in cellulose lignin Populus tremula (a hardwood) Buxus sempervirens softwood), as a result photodegradation Xenon test chamber. The results obtained by means FTIR spectroscopy indicate that is most sensitive component to degradation process for both woods examined. On level, virtual elimination amorphous was observed types wood. crystallised I component, which accounts whole crystalline phase, undergoes minor changes, this effect being more important case less degraded than Sempervirens.
