Resumen:
Samples of fresh and archeological wood were structurally characterized
by XPS and NMR spectroscopy. Archaeological wood chips were recovered
from excavations in the Great Temple of Mexico City. The presence of a
wood consolidant (lactitol trehalose) was studied as a variable, as well
as aging.
Wood samples oxidized after accelerated aging, and hydrolysis was the
first step that promoted oxidation.
Consolidation inhibited hydrolysis and, consequently, oxidation of wood,
whether contemporary or archeological. (C) 2020 Elsevier Masson SAS. All
