| Summary: | Batch adsorption experiments were conducted to evaluate efficiency of lemon peels (Citrus limonum) for adsorption of Acid Red-87 dye from aqueous media. The effects of various parameters, i.e. particle size, pH, sorbent dose, sorbate concentration, temperature, contact time and agitation speed on biosorption efficiency were optimized. Isotherm models: Langmuir and Freundlich were employed to understand the mechanism of adsorption. The monolayer adsorption capacity calculated by Langmuir isotherm was found to be 0.6240 mg/g. Thermodynamic studies revealed exothermic and spontaneous nature of sorption process, while kinetics guided pseudo-second order behaviour. All these factors indicated that Citrus limonum peels are potential adsorbent for the removal of Acid Red-87 |
