Sorption experiments are carried out using sewage sludge for the removal of basic dye basic red-12 from aqueous solution. Effects of process parameters such as initial pH, adsorbent dosage. initial dye concentration, contact time and effect of temperature are investigated. The biosorbent is characterized by FTIR. SEM and XRD. The adsorption of dye is pH dependent. The rate of sorption increases with increase in temperature, and the process is found to be endothermic. Equilibrium is established in 120 min. The pseudo first-order equation, pseudo second-order equation and intraparticle diffusion models are tested. The results showed that the process followed pseudo first order equation very well and intraparicle diffusion plays an important role in the sorption process. The Langmuir and Freundlich equations arc applied to the data related to adsorption isotherm and the observed maximum adsorption capacity was found to be 295.85 mg/g. Thermodynamic parameters: Delta H degrees, Delta G degrees and Delta S degrees are also evaluated. Column experiments are also carried Out to evaluate the hulk removal of color from effluents. The effects of inlet concentration and bed height are evaluated.
