Lucinaldo S. Silva scite author profile

Abstract:The cellulose matrix was characterized by FTIR, 13 C NMR, XRD, TG, SEM and applied in the removal of the reactive red RB dye in an aqueous medium, with a capacity of adsorption at a pH of 2.0, and an adsorption equilibrium time which was reached at around 200 mins. The kinetic study for the system followed the Elovich model. The adsorption isotherms for the system at temperatures of 35°C, 45°C, and 55°C were adjusted to the Langmuir, Freundlich, Sips, and Redlich-Peterson non-linear models, with a capacity of adsorption for adsorbent of 5.97 mg g , respectively. The adsorption occurred by electrostatic interactions and it was favorable and spontaneous, with the influence of temperature.
