Popis:	This work investigates the influence of the condition elaboration of activated carbon (AC) from the Agave Americana fibers (AGF). The best AC is synthesized by impregnating phosphoric acid H3PO4 ratio 40/1 for 6 h at a temperature of 400 °C. Although it has a weak specific surface area, the synthesized AC showed an adsorption capacity toward textile dye Alpacide yellow AY (5.71 mg/g). The latter was higher than that for the commercial AC (CC) (5.27 mg/g). The adsorption process was fast, fractal, and stochastic and follows the kinetic model of Brouers–Sotolongo fractal (BSf) and isotherm model of General Brouers–Sotolongo (GBS).
