“…Brazil is the world leader in orange production, and the country had more than 7.4 million lost orange trees in the eradicated and abandoned grove area in the 2019/2020 harvest, which represented at least one million tons of orange wood. 2 Even with large production, the biomass from trunks of C. sinensis (sweet orange) has still been used mainly for the energy generation by combustion. 3,4 Nevertheless, it is possible to obtain macromolecules such as cellulose and lignins from previously pruned orange trees, trunks, and roots, to obtain a greater added value.…”

“…Determinações experimentais da área superficial específica e dimensões de porosidade podem ser obtidas pelo método de Brunauer-Emmet-Teller (BET) e são cruciais para sustentar as propriedades que foram elucidadas anteriormente a partir de outras técnicas de caracterização (NERIS et al, 2019;PORTO et al, 2021).…”

“…Os grupos funcionais característicos de materiais lignocelulósicos podem ser elucidados (em aspectos qualitativos) através das técnicas de espectroscopia vibracional, tais como a Espectrometria no Infravermelho com Transformada de Fourier (FT-IR) e a Espectrometria Raman. A primeira apresenta uso mais consolidado, baseando-se da diferença do momento de dipolo entre as ligações covalentes, enquanto que a segunda é mais útil para obter informações a curto alcance (pós-adsorção), baseando-se no espalhamento de radiação (Raman) que influencia no grau de polarizabilidade do grupo funcional (ARAUJO et al, 2013;PORTO et al, 2021).…”
