“…Malike Dizbay-Onat et al, investigated the use of sisal fiber residue (Agave sisalana) in the preparation of activated carbon with high surface area and excellent properties in the removal of dyes found in trace amounts in wastewater [20]. Another study using activated charcoal obtained from sisal fiber was carried out by Kahina Bouhadjra when studying textile industrial wastewater, obtaining excellent results removing Cibacron blue dye [21].…”

The economic exploitation of sisal (Agave sisalana) fibers leads to the generation of underutilized waste. Therefore, technologies must be developed to mitigate the environmental impacts caused by inadequate waste disposal and ensure more income from sisal exploration. The present study investigated the potential of agave residues in producing biochar with high adsorbent capacity via slow pyrolysis. Hybrid Itaporanga, Hybrid Bahia, and Mutant-1 hybrid agave varieties were used as precursors and methylene blue (MB) dye was used as a solute. In general, agave residues presented similar contents of lignin (12.1-13.2%) and ash (10.3-13.9%), while the greatest differences were recorded in the values of holocellulose (31.4%-42.4%) and extractives (23.2%-33.4%). The increase in temperature favored an increase in the surface area and volume of micropores in the biochar; however, the adsorption capacity of MB dye was reduced. The pseudo-second-order models effectively adjusted the adsorption kinetics. The Hybrid Itaporanga biochar obtained at 400 °C outperformed the other biochar, presenting static (80 mg.g -1 ) and dynamic (180 mg.g -1 ) adsorption values. Thus, thermochemical valorization of agave residue is attractive to obtain a cheap and environmentally friendly adsorbent.
