Abstract

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 pseudosecond
order behaviour. All these factors indicated that Citrus limonum peels are potential adsorbent for the removal of Acid Red-87.
