“…Increase of temperatures leads to increasing of the sorption capacity, which may be attributed to the enlargement of pore size and activation of the sorbent surface. The negative ΔG° value at all temperatures point out that sorption processes were spontaneous nature and feasible, by increasing the temperature the value of ΔG° becomes more negative, suggesting that higher temperature makes the sorption favorable (Li et al 2015). The positive values of ΔH° (about 10 kJ mol-1) show that the nature of sorption is endothermic and suggest that the sorption is physicochemical process (Elabbas et al 2016).…”

The removal of Cr(III) ions and methylene blue (MB) from aqueous solutions by xanthated corn cob (xCC) in batch conditions was investigated. The sorption capacity of xCC strongly depended of the pH, and increase when the pH rises. The kinetics was well fitted by pseudo-second-order and Chrastil's model. Sorption of Cr(III) ions and MB on xCC was rapid during the first 20 min of contact time and, thereafter, the biosorption rate decrease gradually until reaching equilibrium. The maximum sorption capacity of 17.13 and 83.89 mg g for Cr(III) ions and MB, respectively, was obtained at 40 °C, pH 5, and sorbent dose 4 g dm for removal of Cr(III) ions and 1 g dm for removal of MB. The prediction of purification process was successfully carried out, and the verification of theoretically calculated amounts of sorbent was confirmed by using packed-bed column laboratory system with recirculation of the aqueous phase. The wastewater from chrome plating industry was successfully purified, i.e., after 40 min concentration of Cr(III) ions was decreased lower than 0.1 mg dm. Also, removal of MB from the river water was successfully carried out and after 40 min, removal efficiency was about 94%.

“…Methylene blue, a basic dye, used for dyeing of silk, leather, plastics, paper, and cotton mordant with tannin, as well as for the production of ink and copying paper in the office supplies industry [54][55][56][57][58][59][60][61]. The discharge of this dye to the environment is distressing for both toxicological and aesthetical reasons as dyes impede light penetration, damage the quality of the receiving streams and are toxic to food chain organisms [62].…”

a b s t r a c t Activated carbon, prepared from an agricultural waste, cashew nut shell (CNS) was utilized as an adsorbent for the removal of methylene blue (MB) dye from aqueous solution. Batch adsorption study was carried out with variables like pH, adsorbent dose, initial dye concentration and time. The response surface methodology (RSM) was applied to design the experiments, model the process and optimize the variable. A 2 4 full factorial central composite design was successfully employed for experimental design and analysis of the results. The parameters pH, adsorbent dose, initial dye concentration, and time considered for this investigation play an important role in the adsorption studies of methylene blue dye removal. The experimental values were in good agreement with the model predicted values. The optimum values of pH, adsorbent dose, initial dye concentration and time are found to be 10, 2.1846 g/L, 50 mg/L and 63 min for complete removal of MB dye respectively.

“…In addition, there was an excellent correlation between the calculated amount of MB adsorbed by the SNCM(q e,calc )and the experimental values (q e,exp ) as it is shown in Table 1.These findings confirmed the suitability of the pseudo second order kinetic model for describing the removal of MB dye from the model solution by the SNCM. There are many previous studies showed also the suitability of the pseudo second order kinetic model for the description of MB dye from water by the different solid adsorbents such as; Fe3O4-graphene@mesoporous SiO2 nanocomposites [41], low cost agricultural by-product [40], porous soy protein isolate based composite beads [42], novel manganese oxide nanocorals [43],zeolite synthesized from electrolytic manganese residue [44], zinc oxide nanorods loaded on activated carbon [45], activated carbon [46], poly(sodium p-styrene sulfonate)/poly(methyl methacrylate) particles [47], and many other adsorbents. Also, since the removal of MB dye by the SNCM was fast and followed the pseudo second order kinetic model, the adsorption mechanism could be chemical in nature [48].…”

Abstract:The removal of methylene blue (MB) dye from water was investigated using synthetic nano-clay magadiite (SNCM). SNCM was synthesized by hydrothermal treatment under autogenous pressure. A rosette-shaped single mesoporous magadiite phase with 16.63 nm average crystallite size and 33mBET-surface area was recorded. The adsorption results indicated the pronounced affinity of the SNCM to the MB dye molecules which reached adsorption uptake of 20.0 mg MB dye/g of SNCM. The elimination of MB dye by the SNCM was kinetically and thermodynamically considered; a pseudo second order kinetic model was attained, and a spontaneous, chemical, and exothermic in nature was verified.
