Adsorption of methylene blue from aqueous solution by wheat husk in batch mode
Wheat husk, an agriculture product, was used to adsorb methylene blue (MB) from aqueous solutions. Variables of the system, including contact time, pH, and equilibrium MB concentration, were adopted to study their effects on MB adsorption. The results showed that as the equilibrium concentration of MB increased, quantity of MB sorption onto wheat husk increased correspondingly. The change of MB adsorbed quantity was very small when the pH was increased from 5.0 to 10.0.The equilibrium data was fitted well by the Langmuir model. The adsorption processes followed the pseudo-second-order rate kinetics. The results in this study indicated that wheat husk was an attractive alternaitve for removing cationic dyes from the dye wastewater.
