Abstract EN
Batch adsorption experiments have been conducted to investigate the removal of methyl orange from aqueous solution by an activated carbon prepared from prickly pear seed cake by phosphoric acid activation.
The adsorption process has been described by using kinetic and isotherm models.
The kinetic of adsorption was examined by pseudo-first-order, pseudo-second-order, and intraparticle diffusion models.
Adsorption isotherm was modeled using Langmuir, Freundlich, Temkin and Dubinin–Radushkevich isotherms.
The adsorption process of methyl orange was well explained by the pseudo-second-order model and Freundlich isotherm.
Also, pseudo-n-order model has been applied to estimate the order of adsorption kinetic and it was found equal to 2 which confirm the good accuracy of the pseudo-second order.
Moreover, Dubinin–Radushkevich isotherm reveals that the adsorption of methyl orange onto activated carbon was a physisorption process in nature.
The adsorption capacity of activated carbon was found to be 336.12 mg/g at temperature 20°C and pH∼7.
These results demonstrated that the prickly pear seed cake is a suitable precursor for the preparation of appropriate activated carbon for dyes removal from aqueous solution.
