“…Partial gasification using water vapor, carbon dioxide, or their mixtures increases the surface area in activated carbons [5,6]. However, chemical activation with acids or alkalis, among other chemical compounds, have been also reported to improve the surface area in ACs [7][8][9][10][11][12][13][14]. Wei et al [15] observed higher specific surface area (SSA) values with large mesoporous volume when KOH was used.…”

Activated carbon (AC) was gained from Pinus montezumae (PM) wood sawdust and chemical activation with K2CO3 was used for obtaining activated carbons. Variations in reaction conditions such as temperature, impregnation ratio (IR), and activation time were carried out to study their influence on the specific surface area (SSA) and average pore volume (APV) in AC. Materials were analyzed by means of Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X‐ray diffraction (XRD) to determine the functional groups, pore structure, and morphology of pine sawdust and activated carbons. Activated carbons were amorphous in nature with some crystalline regions.

The objective of this study was to evaluate the characteristics of mangium bark and its biosorbent ability to reduce heavy metal ions in standard solutions and wastewater and to assess changes in bark characteristics after heavy metal absorption. The experiments were conducted to determine heavy metal absorption from solutions of heavy metals alone and in mixtures as well as from wastewater. The results show that mangium bark can absorb heavy metals. Absorption percentages and capacities from single heavy metal solutions showed that Cu(2+) > Ni(2+) > Pb(2+) > Hg(2+), while those from mixture solutions showed that Hg(2+) > Cu(2+) > Pb(2+) > Ni(2+). Wastewater from gold mining only contained Cu, with an absorption percentage and capacity of 42.87 % and 0.75 mg/g, respectively. The highest absorption percentage and capacity of 92.77 % and 5.18 mg/g, respectively, were found for Hg(2+) in a mixture solution and Cu(2+) in single-metal solution. The Cu(2+) absorption process in a single-metal solution changed the biosorbent characteristics of the mangium bark, yielding a decreased crystalline fraction; changed transmittance on hydroxyl, carboxyl, and carbonyl groups; and increased the presence of Cu. In conclusion, mangium bark biosorbent can reduce hazardous heavy metal ions in both standard solutions and wastewater.

“…is one of the most planted species of Acacia genus and the bark is used for tannin extraction. However, the biomass of this species, including bark, has been used for energy purposes in various regions of the world (POHLMANN et al, 2014;MARQUEZ-MONTESINO et al, 2015;CHARUSIRI et al, 2017). Thus, may be an alternative for forestry plantations for energy purposes, especially for it presents rusticity and adaptability to adverse soil and climate conditions, rapid growth and high biomass production (DUARTE et al, 2011).…”

ResumoA presença da casca na madeira de Acácia mangium melhora o seu potencial energético. A utilização da casca associada com a madeira de espécies florestais, para a geração de energia, pode ser uma alternativa viável do ponto de vista técnico, ambiental e econômico. O trabalho teve como objetivo avaliar o efeito da adição da casca nas características da madeira e de briquetes de Acácia mangium e Eucalyptus urophylla x Eucalyptus grandis (urograndis). Árvores das duas espécies, com 7 anos de idade, foram cortadas de experimento de campo e obtidas amostras de madeira com e sem casca para a avaliação das características físico-energéticas da biomassa e briquetes. A presença da casca na madeira da A. mangium melhorou as suas características energéticas, sendo viável do ponto de vista técnico a sua utilização, em pequenas quantidades, em conjunto com a madeira para aplicações energéticas. A adição da casca em pequenas quantidades na madeira do Urograndis promoveu a redução das suas características energéticas. As características dos briquetes não foram influenciadas pela espécie e presença da casca.
