“…An example is an adsorption-membrane filtration hybrid process where ion exchange resins are coupled with membrane filtration for water purification [101,102]. Cermikil et al [103] investigated the performance of NMDG-functionalized boron-selective ion exchange resins against the commercial boron-selective Dowex XUS 43594 resin. In contrast to the boron removal capacity of Dowex XUS 43594, which is 0.52 mg/L with 95.3% efficiency, the NMDG-functionalized resin yielded 1 mg B/L after 60 min with a boron removal rate of 92%.…”

Boron is an essential micronutrient that has raised much interest, given the narrow balance between its necessity and toxicity. Both natural and anthropogenic emissions of boron into water sources can eventually deteriorate water quality and endanger the ecosystem. In this review, we first present a general outline of the importance of boron, boron chemistry in water, boron contamination, and its consequences followed by the recent progress in boron removal methods based on adsorption. The adsorbents for deboronation can generally be classified based on the functional groups present; chelating groups, metal oxides, and layered double hydroxides. To comprehensively address these adsorption methods, a detailed discussion on the reaction mechanism of each system is done followed by a summary of the progress in the field during the past 5 years. Finally, some characterization techniques used in deboronation studies and suggestions for future research and applications together with possible improvements to the existing systems are presented.

“…Organic As species including dimethyl arsenic acid, monomethylarsonic acid and arsenobetaine are about 70 times less toxic than inorganic As species [5]. Various processes have been studied to remove As from contaminated water, including nanofiltration [6], electrochemical techniques [7], chemical precipitation [8], ion exchange [9], and membrane separation [10]. Production of excess sludge, high cost and energy requirement, incomplete removal of pollutants, high chemical requirements and high costs of operation and maintenance are disadvantages of previous methods [11].…”

An amino-functionalized MIL-68(Al) metal-organic framework (amino-MIL-68(Al) MOF) was synthesized by solvothermal method and then characterized by FESEM, XRD, FTIR, EDX-mapping, and BET-BJH techniques. In order to predict arsenate (As(V)) removal, a robust quadratic model (R2 > 0.99, F-value = 2389.17 and p-value < 0.0001) was developed by the central composite design (CCD) method and then the genetic algorithm (GA) was utilized to optimize the system response and four independent variables. The results showed that As(V) adsorption on MOF was affected by solution pH, adsorbent dose, As(V) concentration and reaction time, respectively. Predicted and experimental As(V) removal efficiencies under optimal conditions were 99.45 and 99.87 %, respectively. The fitting of experimental data showed that As(V) adsorption on MOF is well described by the nonlinear form of the Langmuir isotherm and pseudo-second-order kinetic. At optimum pH 3, the maximum As(V) adsorption capacity was 74.29 mg/g. Thermodynamic studies in the temperature range of 25 to 50 °C showed that As(V) adsorption is a spontaneous endothermic process. The reusability of MOF in ten adsorption/regeneration cycles was studied and the results showed high reusability of this adsorbent. The highest interventional effect in inhibiting As(V) adsorption was related to phosphate anion. The results of this study showed that amino-MIL-68(Al) can be used as an effective MOF with a high surface area (> 1000 m2/g) and high reusability for As(V)-contaminated water.
