Evaluation of Salt-Induced Damage to Aged Wood of Historical Wooden Buildings

Figure 5

XANES spectra of the aged and sound samples. The dominant peak is sulphate (2481.6 eV), and the two additional peaks at 2472.6 and 2475.3 eV in the sound sample spectrum can be attributed to the reduced forms of sulphur such as aliphatic sulphide and thiophene.
