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

Figure 4

(a) XRF spectra of the aged and sound wood samples, where the well-resolved peaks of sulphur, chlorine, potassium, calcium, and iron ion can be detected. (b) Area integration percent of the elements in the aged and sound wood samples. The aged samples (9F6, 8F11, 7F17, 5F23, and 4F27) contain more inorganic element content than the sound sample, particularly the contents of calcium, sulphur, chlorine, and iron ions.
