Behavior of the adsorption of Allura Red dye by chitosan beads and nanoparticles

Adsorptive removal of synthetic food dyes using low-cost biochar: Efficiency prediction, kinetics and desorption index evaluation

“…Notably, the appearance of sharp peaks at 2930 and 1030 cm − 1 for ARFD adsorption. Similar findings have been documented (Al Shamari et al, 2020;Reyna G et al, 2023;Saha et al, 2020).…”

“…Isotherm modelling is useful for observing the relationship between BSAB and the investigated food dyes at equilibrium. A thorough knowledge of this will greatly improve the design of the adsorption system, effluent treatment reactor, and BSABdye interaction pattern (Dada et al, 2021b;Katiyar et al, 2021;Reyna G et al, 2023). The initial concentration equilibrium data were analysed using the Langmuir, Freundlich, Dubinin-Radushkevich, and Redlich-Peterson mathematical isotherm models.…”
