Interpretive Summary: Activated carbon was produced from sawdust residues of massaranduba wood from Brazil. The activated carbon adsorbed more moisture and was more thermally stable than raw wood. It was also highly porous with many nano and micropores, leading to a large surface area. This makes it an ideal material for filtering polluted waste water.

Technical Abstract: The aim of this study was to evaluate the microstructural, thermal and physical characteristics of activated carbon produced from sawdust residues of massaranduba (Manilkara huberi) wood. Activated carbon was obtained and their properties were compared with the starting wood and charcoal (before activation). Microstrutural, thermal and physical properties of these sample treatments were evaluated. The activated carbon had higher reactivity with moisture, lower crystallinity and higher thermal stability compared to its wood and charcoal precursors. SEM images showed the formation of nanoscale pores after the activation treatment of charcoal. DSC was effective in detecting the changes in the moisture adsorption and heat of dehydration. The present study contributed important information about the production and characterization of activated carbons from Amazonian commercial wood residues.
