Description

The adsorption of Methylene blue and Methyl orange by date pits carbon was carried out by varying parameters such as agitation time, pH and dye concentration. Equilibrium adsorption data followed both Langmuir and Freundlich isotherms. Adsorption followed second-order rate kinetics. The adsorption capacity was found to be 434 and 455mg of methyl orange and methylene blue, respectively, per g of the date pits carbon. Acidic pH is favorable for the adsorption of methyl orange against a basic medium which is favorable for the adsorption of MB. An opposite result was found for the methylene blue adsorption
