This paper describes the sorption kinetic and isotherm of methylene blue (MB) by thermally treated alum sludge (TAS) at the laboratory scale. Kinetics study was conducted by varying initial concentrations of MB (50, 150 and 250 mg/L) and contact time (30, 60, 120 and 180 min) whereas adsorption isotherm was investigated at various initial concentrations (10, 50, 100, 200, 300 and 400 mg/L) at constant temperature (25oC), contact time and agitation speed. Lagergren, Ho and Mckay and intra-particle diffusion kinetics modes were applied to the experimental data while the adsorption isotherms are described by Langmuir and Freundlich and Temkin isotherm models. The results showed that sorption kinetics and isotherm of MB were best described by Ho and Mckay kinetics model and Langmuir isotherm model, respectively. The maximum adsorption capacity (qm) obtained from Langmuir plot was 25.445 mg/g. It can be concluded the adsorption of MB by TAS is monolayer adsorption.
