“…An adsorption capacity of 70.92 -344.83 mg/g was found for Cu 2+ by prepared sorbents from peel wastes. The adsorption of MB by green pea peel (GPP) and acid-treated carbon (GPP-AC) has been reported [135]. Physico-chemical characteristics of GPP are summarized in Table 5.…”

“…More than 10×10 5 commercially available dyes with over 7×10 5 tons of dyestuff are produced per year (Pearce 2003), and about 10 to 15% of the used dye is lost in the effluent of textile units (Dod et al 2012;Husain 2006). Many dyes have toxic, carcinogenic, mutagenic, and teratogenic effects on aquatic life and also on humans (Bhattacharyya and Sharma 2005;Chatterjee et al 2009).…”

Spent mushroom substrate (SMS), a renewable bio-waste from the mushroom-growing industry, was used as an adsorbent to remove methylene blue (MB) from aqueous solution. SMS was characterized using scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). Adsorption experiments with the SMS adsorbent were performed based on various parameters, such as adsorbent dose, initial MB dye concentration, initial pH, contact time, and temperature. The Langmuir, Freundlich, and Temkin isotherm models were employed to interpret the adsorption behavior. The results indicated that the equilibrium data were perfectly represented by the Temkin isotherm. The maximum adsorption capacity of SMS reached 63.5 mg g -1 at 303 K. The kinetics studies indicated that the pseudo-second-order model best described the adsorption of MB on SMS. The activation energy of the adsorption was 5.64 kJ mol -1 . Thermodynamic parameters suggested that the adsorption was an exothermic and spontaneous physical process. The results imply that SMS is a potentially low-cost adsorbent for treating wastewater containing cationic dyes.

“…The use of soy hull as adsorbent would not only reduce environmental problems but also produce value-added products. However, soy hull possesses low effective functional groups [3]. Polyamidoamine dendrimer are offering new opportunities to prepare more attractive functional materials for adsorption organic dyes and metal ions.…”

Abstract. In this work, the soy hull has been modified with polyamdioamine dendrimer to prepare a kind of new adsorbents possessing abundant nitrogen functional groups. The adsorption behaviors of the modified soy hull for methyl blue (MB), acid fuchsine (AF), and malachite green (MG) were studied. The removal efficiency of the three organic dyes was in the order of AF>MB>MG, and its values increased with increasing contact time. The adsorption kinetics was studied by pseudo-first-order and pseudo-second-order kinetics models, and the adsorption isotherms were studied by Langmuir and Freundlich isotherm. The pseudo-second-order model and Freundlich isotherm were found to fit well the adsorption processes of the modified soy hull. Thermodynamic data of the adsorption processes were also calculated according to the adsorption thermo-chemistry between the modified soy hull and organic dyes molecules. The values of △G θ (for MB, AF and MG) are negative, which shows that the adsorption process is spontaneous. The positive value of △H θ indicates that the adsorption is endothermic and higher temperature makes the adsorption easier. The positive value of △S θ indicated that the randomness is increased at the solid-solution interface during adsorption process.
