“…Adsorption is commonly used for removal of IC. Several researchers have extensively tried different sorbent materials such as cetyltrimethylammonium bromide‐modified TiO 2 nanoparticles, activated carbon doped with biogenic manganese oxides, weak base anion exchanger Amberlite FPA51, magnesium hydroxide, Ni‐nanoscale oxides/ Schoenoplectus acutus composite, microwave‐treated activated carbon from peanut shells for effective removal of IC.…”

In the present study, crosslinked egg white is used as a low‐cost biosorbent for removal of a toxic dye, indigo carmine. The biosorbent preparation is easy and only N,N′‐methylenebis(acrylamide) is added for crosslinking. The characterization of the prepared material is done with scanning electron microscopy and IR spectroscopy. The surface charge is determined with point of zero charge method. The prepared biosorbent is used for removal of indigo carmine. The experimental parameters (e.g., pH of solution, initial dye concentration, time) are optimized to achieve quantitative removal. The biosorption data of indigo carmine on crosslinked egg white is fitted with the Langmuir model with a Qmax value of 67.56 mg g−1. The kinetic data are treated with pseudo‐first‐ and second‐order models. The second‐order model best explains the kinetic behavior of the process. The quantitative extraction of indigo carmine is achieved for 25 mg g−1 of IC within 30 min at pH 2. The crosslinked egg white can be used several times after regeneration.

“…Sadly, about 15% of the total world production of dyes is lost during the dyeing process and is released in the textile effluents (Jose et al 2013); hence, the growing need to protect the environment from these harmful chemicals. Over the years, a lot of techniques were used to treat the textile wastewater and solve the problem of industrial effluents, such as biological treatment (Agostina et al 2014), adsorption (Ramesh and Sreenivasa 2015), ozonation (Ahao et al 2006), coagulation-flocculation (Guibal and Roussy 2007) and membrane filtration (Goksen and Yetis 2006). These methods are rather costly and little efficient (Mollah et al 2004).…”

In this study, we investigated the effect of alternating current (AC) and direct current (DC) on the elimination of methylene blue (MB) and indigo carmine (IC) by the electrocoagulation process using two Pb electrodes in comparison with the coagulation-flocculation process. Different parameters influencing the elimination of these dyes were studied, namely initial dye concentration, initial pH, voltage, temperature, coagulant and flocculant concentration and current density. The elimination of MB reached 98.8% with AC and 97.3% with DC at current density of 0.5 A/m 3 and pH of 7.0. However, the energy consumed was lower in the case of AC (4.89 9 10 -6 kWh/m 3 ) than DC (7.6 9 10 -6 kWh/m 3 ). The elimination was also faster in the case of AC (0.47 mg L -1 /min) than the DC (0.066 mg L -1 /min). The same behavior was observed with the IC where the effectiveness of dye elimination was, respectively, 98.5 and 100% with an energy consumed (E c ) of 4.35 9 10 -5 and 2.03 9 10 -6 kWh/m 3 , respectively, with DC and AC. The adsorption kinetic data were obtained using pseudo-firstorder and pseudo-second-order models. The pseudo-second-order was more appropriate describing the adsorption kinetics of methylene blue and the pseudo-first-order was more appropriate describing the adsorption kinetics of indigo carmine. Langmuir, Freundlich and Sips models were used to optimize the elimination dye process. The Sips model displayed the best fit of the equilibrium data.

“…Formed Mg(OH) 2 also acts as an adsorbent for removal of dye. There are few reports on Mg(OH) 2 as an adsorbent [34,35]. Also, it makes the strong H bond with dye molecules which leads to a strong adsorption.…”

Nanospherical and plate-like magnesium oxide has been successfully synthesized by urea precipitation method for the first time. A magnesium oxide precursor was prepared by heating MgCl2 solution with urea for 12 hours at 90°C. Then the calcined precursor was analysed by Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), and high-resolution transmission electron microscopy (HR-TEM). In the presence of the nonionic surfactant Triton X-100 in the system, the reaction yielded in nanospheres of MgO contrast to the plate-like MgO in the absence of the surfactant. The precursor and the calcined product appeared in similar morphologies under SEM in both cases with a slight reduction of size upon calcination. The final product was confirmed as MgO using XRD and FT-IR spectroscopic methods. In TGA, both samples showed similar mass loss values upon elimination of adsorbed water molecules and decomposition of the precursor into MgO; however, the nanospherical MgO sample showed an additional weight loss due to elimination of the associated surfactant molecules. The efficiency of removing reactive dye wastes was quantified by UV-visible spectroscopy using reactive yellow dye. Plate-like MgO showed a porous structure under HR-TEM analysis in the dye adsorption study, and both plate-like and nanospherical MgO showed good dye adsorption capability. MgO nanospheres showed higher capacity of dye adsorption compared to plate-like MgO, explained by its higher surface are-to-volume ratio, while the plate-like MgO also performed well due to having a nanoporous structure. These nanomaterials will offer high potential in purifying waste water and as well in recovering expensive dye products.
