Fourier transform infrared spectroscopy in treated woods deteriorated by a white rot fungus

Abstract: This study aimed to analyze chemical changes by Fourier Transform Infrared Spectroscopy of Eucalyptus dunnii and Pinus elliottii treated woods subjected to an accelerated decay test with the white rot fungus Ganoderma applanatum. The wood test specimens (2,5x2,5x0,9 cm) were impregnated wi...
