Effect of UV-Irradiation on Surface Color and Chemical Structure of Wood

Abstract:

Article Preview

The changes of the surface colors and chemical constituents of Mongolian Scotch pine treated by UV light were investigated by spectrophotometer and FTIR followed by acid pretreatment. The results show that the changes of the surface colors are related to carbonyl, aromatic nucleus, arone, Ar-OH, paraquinones, ortho quinine and so on in the course of UV irradiation. Acid promotes photocycloaddition and plays a hyperchromic effect.
