Thermodynamic Study of Adsorption Cationic Methylene Blue Dye on the Plant Residue
Abstract
Equilibrium adsorption isotherm for the removal of basic dye Methylene Blue from aqueous solution using dates seeds-activated carbon and sawdust wood were studied. The effects of various experimental parameters such as contact time, effect of pH and adsorbent dosage and temperature of dye solution on the adsorption capacities have been investigated. The result shows the isotherms were S3 on dates seeds - activated carbon and S4 on sawdust wood according to Giels classification. Adsorption data was better fitted to the Langmuir and Freundlish isotherm on sawdust and fitted to the Freundlish only on activated carbon. The thermodynamic parameters such as ∆H°, ∆G° and ∆S° of adsorption were calculated. The result in this study indicated that activated carbon from dates seeds and sawdust wood were attractive candidate for removing cationic dyes from the dye wastewater.
