“…It can also be observed that the lines do pass by the origin (C = 0.737 to 28.789), and this indicates that the transfer mechanism is controlled not only by intra-particle diffusion but also by other mechanisms, such as boundary layer [57]. Similar results have been reported for the biosorption of MB onto activated carbons prepared from NaOH-pretreated rice [71], Luffa cylindrica fiber-activated carbons [72], sugar beet pulp [21] and low cost biomass material lotus leaf [73].…”

“…Recently, inexpensive, ecofriendly and not pathogenic organisms have been used for the dye removal [18]. In this respect, the biosorption process has attracted a great interest in this context, and seems a good alternative for the removal of dyes and other pollutants from wastewaters [19,20], as a replacement for costly commercially biosorbents [21]. It can be defined as sequestering of organic or inorganic compounds by alive or dead biomasses or their derivatives; the biomass can consist of bacteria [22], fungal [19], yeasts [22], algae [23], seaweeds and even industrial or agricultural wastes [24,25].…”

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.

“…Compared with the work which used sugar beet pulp as sorbent (Vučurović et al 2012), SBPAC showed a weaker adsorbance and this may be caused by the existing of functional group in precursor. Similar results were obtained from contrast of various agro-industrial waste materials and resulted AC (Table 2).…”

Sugar beet pulp is an abundant, renewable and low-cost precursor for production of activated carbon. In the present study, sugar beet pulp based activated carbon was prepared by using phosphoric acid as activating agent for adsorption of methylene blue. The conditions of preparation process had a significant influence on the adsorption of methylene blue, and the optimal preparation conditions were obtained as follows: liquid-to-solid ratio of 5, temperature of 450°C and phosphoric acid concentration of 3 mol/L. The properties of sugar beet pulp based activated carbon were characterized by nitrogen adsorption isotherm. The adsorption increases as the increase of contact time, adsorption temperature and pH, and initial concentration of methylene blue. Batch kinetic studies showed that an equilibrium time of 100 min was needed for the adsorption, and the adsorbance of methylene blue is 244.76 mg/g at equilibration. Kinetic models, Weber's pore diffusion model and Boyd's equation were applied to the experimental data to study the mechanism of adsorption and the controlled step. The results showed that the adsorption kinetics followed the pseudosecond-order type kinetic model, intraparticle diffusion was not the rate-limiting mechanism and adsorption process was controlled by film diffusion.

“…MB is a toxic dye and causes several health risks in humans upon exposure such as nausea, vomiting, eye injury, and methemoglobinemia (Al-Anber et al 2011;Dutta et al 2011;Vucurovic et al 2012). Thus, it is important to remove MB dye from industrial wastewater.…”

The objective of this study was to investigate the biosorption of an azo dye (Methylene blue) by a wetland phytomass (Typha angustata) under post-phytoremediation scenario. Thus, the phytomass was used without any chemical modification. The batch adsorption experiments were conducted to evaluate the effects of contact time and temperatures (25-45°C) on the adsorption of methylene blue (MB) from aqueous solution by cattail phytomass (CP). More than 80 % of MB dye was removed from the aqueous solution within first 10 min of the experiment. Langmuir isotherm was modeled to describe the monolayer adsorption of MB dye (R 2 = 0.995) with the maximum adsorption capacity of 8.1 mg/g at 25°C. Pseudo-second-order kinetic model adequately described the kinetics of absorption process (R 2 = 0.999). The adsorption of MB on the cattail phytomass was a spontaneous and endothermic process that was governed by chemisorption. Hence, CP could be applied as a potential low cost biosorbent to treat dyeing wastewater.
