“…The percentage removal of MO from aqueous solution was decreased from 93% to 25 % by increasing the initial concentration of dye from 100 to 1000 mg/L. It was associated with the fact that the active sites of the DMEA-grafted AEM became saturated by increasing the initial concentration of dye, which resulted in a decrease in the percentage removal of dye from aqueous solution [13]. On the other hand, the adsorption capacity of the DMEA-grafted was increased from 19 to 100 mg/g by increasing the initial concentration of dye from 100 to 1000 mg/L.…”

“…From these reported technologies, adsorption for wastewaters treatment is recognized as easy as pie due to its simple and low-cost method [12]. Moreover, it is an environment-friendly alternative due to room temperature and pressure and simultaneous discharge of dyes [13,14]. It gives an extraordinary surrogate for the treatment of wastewater, particularly when the adsorbent is reasonable and does not demand further pretreatment steps before its utilization [13,15].…”

This manuscript describes the synthesis of dimethylethanolamine (DMEA)-grafted anion exchange membrane (AEM) by incorporating dimethylethanolamine as ion-exchange content into the polymer matrix via the solution casting method. The synthesis of the DMEA-grafted AEM was demonstrated by Fourier transform infrared (FTIR) spectroscopy. The prepared DMEA-grafted AEM exhibited higher thermal stability, homogeneous morphology, water uptake (WR) of 115%, and an ion exchange capacity (IEC) of 2.70 meq/g. It was used for the adsorptive removal of methyl orange (MO) from an aqueous solution via batch processing. The effect of several operating factors, including contact time, membrane dosage, initial concentration of aqueous dye solution, and temperature on the percentage discharge of MO and adsorption capacity, was evaluated. Experimental data for adsorption of MO onto the DMEA-grafted AEM was analyzed with two parameter and three parameter nonlinear adsorption isotherm models but fitted best using a nonlinear Freundlich isotherm. Adsorption kinetics were studied by using several models, and attained results showed that experimental data fitted well to pseudo-second-order kinetics. A thermodynamic study showed that adsorption of MO onto the prepared DMEA-grafted AEM was an endothermic process. Moreover, it was a feasible and spontaneous process.

In this research, the development of a novel brominated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO)-based homogeneous anion exchange membrane (AEM) via the solution casting method was reported. Fourier transform infrared spectroscopy was used to confirm the successful development of the BPPO-based AEM. The prepared AEM showed excellent thermal stability. It exhibited an ion exchange capacity of 2.66 mg/g, a water uptake ( W R ) of 68%, and a linear swelling ratio of 31%. Methyl orange (MO), an anionic dye, was used as a model pollutant to evaluate the ion exchange ability of the membrane. The adsorption capacity of MO increased with the increase in contact time, membrane dosage (adsorbent), temperature, and pH while declined with the increase in initial concentration of MO in an aqueous solution and molarity of NaCl. Adsorption isotherm study showed that adsorption of MO was fitted well to the Freundlich adsorption isotherm because the value of the correlation coefficient ( R 2 = 0.974) was close to unity. Adsorption kinetics study showed that adsorption of MO fitted well to the pseudo-second-order kinetic model. Adsorption thermodynamics evaluation represented that adsorption of MO was an endothermic (Δ H ° = 18.72 kJ/mol) and spontaneous process. The AEM presented a maximum adsorption capacity of 18 mg/g. Moreover, the regeneration of the prepared membrane confirmed its ability to be utilized for three consecutive cycles. The developed BPPO-based AEM was an outstanding candidate for adsorption of MO from an aqueous solution.

The present study is interested in removal of a cationic dye gentian violet (GV) using a polystyrene membrane (PS) activated with oleic acid (OA). These innovative membranes were developed by using PS as the base polymer and OA as extractant. The best matrix obtained was characterized by using Fourier transform infrared spectroscopy (FTIR) and x‐ray diffraction (XRD), and then applied in the extraction of a cationic GV dye. The effects of an extraction ratio (OA/PS) in the PS‐AO matrix, initial GV dye concentration ([GV]0), and pH of the solution were studied in a batch reactor. The thermodynamic parameters (, , and ) have been calculated. Therefore, the GV extraction onto the PS‐OA matrix is an exothermic and spontaneous process. In addition, the slop method confirms that the chemical formula of the extracted OA‐GV complex is GV‐RHR. The central composite design (CCD) was used to determine the conditions of each experimental run, and extraction optimization was achieved using response surface methodology (RSM). The results showed that the quadratic regression model was statistically significant (0.9994), and the parameters studied had a profound effect on the extraction efficiency. The optimum GV extraction efficiency of 99% was achieved at an extractant ratio of 1, pH of 8, and [GV]0 of 10 mg L−1. The findings of the current study reveal that PS‐AO matrix is an advantageous and effective membrane for the extraction of GV from aqueous solutions, both environmentally and economically, it can be regenerated and used up to five times.
