Superior performance for dye removal has been achieved by modification of natural fibers with amine incorporation, while the presence of functional groups, such as hydroxyl, carboxyl, and carbonyl, in corn fibers and the lignocellulose residue from sugarcane bagasse resulted in outstanding performance for trace metal ion removal.…”

“…The use of fibrous conductive supports favors the use of electro-adsorption as an efficient method for dye removal. [111] Moreover, porous bulky structures have been developed from synthetic foams for the selective removal and detection of specific Ref.…”

Electrochemical/Peroxymonosulfate/NrGO-MnFe2O4 for Advanced Treatment of Landfill Leachate Nanofiltration Concentrate

“…However, the cost of the treatment equipment is high because the ultraviolet assistance cannot effectively use sunlight. Electrochemistry, which is easy to combine with other technologies, has many advantages, such as high flexibility, clean processing process, simple equipment and easy control, so it has received more and more attention [10,11,24]. In the process of electrochemical activation, PMS can directly obtain electrons at the cathode and convert them into SO 4…”

“…(Equations (1) and (2)) [24]. However, a single electrochemical system usually requires a longer reaction time and a larger current density to achieve a satisfactory degradation effect, so the combination of metallic [10] or non-metal [11] catalysts can still achieve an ideal treatment effect in a shorter time and a smaller current density. Thus, it was creatively assumed that nitrogen-doped GO (NrGO) supporting MnFe 2 O 4 as the catalyst of the electro-activated PMS process would exhibit better performance through the coupling of the three.…”

Nanocellulose–organic montmorillonite nanocomposite adsorbent for diuron removal from aqueous solution: optimization using response surface methodology

“…In addition, although electrochemical oxidation exhibits a notable treatment effect and rapid reaction, it requires specic electrolytes, which increases the treatment cost. 24 In comparison, the adsorption method has the advantages of simplicity, high efficiency, exibility, and low cost, and it is currently the most feasible and the most environmentally friendly method. To date, activated carbon, 25 ionic liquids, 26 magnesite, 27 and zeolite Y 28 have been used to remove DUR from water.…”
