In the present study, biomass fiber (Luffa cylindrica) has been successfully used as biosorbent for the removal of a cationic dye namely, methylene blue, from aqueous solution using a batch process. The characterization of the biosorbent was carried out by the infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The chemical composition has been established by the energy dispersive X-Ray spectroscopy (EDS). The effects of various parameters such as the contact time (0-160 min), solution pH (2-10), biosorbent dose (0.5-8 g L -1 ), particle size, initial MB concentration (20-300 mg L -1 ) and temperature (20-60°C) were optimized. The biosorption isotherms were investigated by the Langmuir, Freundlich, Dubinin-Radushkevich and Tempkin models. The data were well fitted with the Langmuir model, with a maximum biosorption capacity of 49.46 mg g -1 at 20°C. The kinetics data were analyzed by the pseudo-first-order and pseudo-second-order models. The mass transfer model in terms of interlayer diffusion was applied to examine the mechanisms of the rate-controlling step (R 2 = 0.9992-0.9999). The thermodynamic parameters: free energy (DG°= -5.428 to -3.364 kJ mol -1 ), enthalpy (DH°= -20.547 kJ mol -1 ) and entropy (DS°= -0.052 kJ mol -1 K -1 ) were determined over the temperatures range (20-60°C). The results indicate that Luffa cylindrica could be an interesting biomass of alternative material with respect to more costly adsorbents used nowadays for dye removal.
