This paper characterizes wood and charcoal made from Hymenaea au- rea, Mimosa scabrella, Tabebuia capitata and Eucalyptus alba by scanning electron microscopy and near infrared for the purpose of developing a technique to identify the source of charcoal samples. Ten test samples were prepared for each species, oriented in transverse, radial and tangential section. Samples were carbonized in a muffle furnace with a final temperature of 450 °C and a heating rate of 1.66 °C/min. The microscopic structures of the wood and charcoal samples were verified by scanning electron microscopy, and spectra were obtained with a spectrophotometer, equipped with an integrating sphere and operating in transmittance mode. The spectra of the wood samples present characteristic bands of lignocellulosic material, while the spectra of the charcoal samples show small or nil absorption in the near- infrared region. The near-infrared spectroscopy technique was efficient in dis- criminating the four species studied. |
