“…Few investigations have been reported regarding the removal of MO dye through PEUF [ 2 , 18 , 77 , 78 ]. Fradj et al studied the removal of MO by PEUF, using chitosan (CHI) with a molecular weight of 117 kDa, obtaining a retention rate of 86% at pH 4.5 at 25 °C with a polymer dose of 0.4 mM and an initial MO concentration of 0.1 mM (32 mg L −1 ) [ 2 ].…”

“…In addition, apart from MB and MO, PEUF has been used in the removal of several ionic dyes such as: direct blue 71 (DB71), EBBR, RR 120, acid-orange 7 (AO7), carmine indigo (IC), amide black (AB), direct black (DB), reactive black 5 (RB5), acid blue 129 (AB129), orange II (OII), ethyl orange (EO), ST, malachite green (MG), bright green (BG), new fuchsia (NF), CV, MB, toluidine blue (TB), and acridine yellow (AY) [ 2 , 6 , 18 , 21 , 31 , 60 , 63 , 73 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 ]. Table 1 shows the classification of the dyes according to their chemical speciation in solution and their molecular structure.…”

“…Through a systematic study of the literature, 24 scientific reports related to the removal of dyes by PEUF were found between 1986 and the year 2021, revealing the few publications on this subject. It should be noted that the dye most studied so far is MB [ 28 , 31 , 33 , 74 , 75 , 76 ], followed by MO [ 2 , 18 , 77 , 78 , 79 ].…”

The current problem of contamination caused by colored industrial effluents has led to the development of different techniques to remove these species from water. One of them, polymer-enhanced ultrafiltration (PEUF), has been systematically studied in this mini review, in which research works from 1971 to date were found and analyzed. Dye retention rates of up to 99% were obtained in several cases. In addition, a brief discussion of different parameters, such as pH, interfering salts, type of polymer, dye concentration, and membrane type, and their influence in dye removal is presented. It was concluded from the above that these factors can be adapted depending on the pollutant to be remediated, in order to optimize the process. Finally, theoretical approaches have been used to understand the intermolecular interactions, and development of the studied technique. In this revision, it is possible to observe that molecular docking, molecular dynamics simulations, density functional theory calculations, and hybrid neural-genetic algorithms based on an evolutionary approach are the most usual approximations used for this purpose. Herein, there is a detailed discussion about what was carried out in order to contribute to the research development of this important science field.

The aim of this study to determine the usability of cetyltrimethylammonium bromide (CTAB)reduced graphene oxide (RGO) composites in the removal of methylene blue (MB) from aqueous solutions and to investigate the stability of composites in the aqueous dispersions. And also, we compared the effects of three different CTAB concentrations on the decolorization of MB. The CTAB-RGO composites performed increasing decolorization activity, decreasing average particle size and resulting individual graphene layers with the increasing CTAB concentration. CTAB-RGO with 40 and 80 mg/L composites were unstable, RGO and CTAB-RGO with 120 mg/L had good stability in the aqueous solutions. Effective repulsive forces of CTAB-RGO-120 composite prevented to forming graphene aggregates. The highest decolorization rate of CTAB-RGO-120 composite at neutral pH can result from both the electrostatic interaction and π-π interaction.

“…In past few decades, with the advantages of high efficiency and no secondary pollution, complexation-ultrafiltration process has been proved to be a promising alternative for metal removal and recovery [12][13][14]. It has been successfully used for treating Ni 2+ , Zn 2+ , Cd 2+ , Co 2+ , Cu 2+ , Pb 2+ , Hg 2+ and other heavy metal ions in the laboratory [15][16][17][18], whereas it is relatively unexplored in recovering Sn 2+ . In the previous studies, lots of complexing agents such as polyethylene imine [19], polyacrylate sodium [20], polyvinyl alcohol [21,22] and the copolymer of maleic acid-acrylic acid (PMA) [23], have been used in many researches.…”

Commercially available polymer, the copolymer of maleic acid and acrylic acid (PMA), was used for the efficient removal of Sn 2+ from aqueous solutions by complexation-ultrafiltration. The rejection of Sn 2+ reached up to 99.3% at pH 5.0 and P/M (the mass ratio of polymer to metal ions) 5. The study was the first to examine the kinetics of complexation reactions of PMA with Sn 2+. It takes 35 min for Sn 2+ to get the complexation equilibrium, and the reaction kinetics can be described by a pseudo-first-order equation. The stability of PMA-Sn complex in the shear field was studied for the first time. The critical rotating speeds at which the PMA-Sn complex began to dissociate were 1960, 1680, 1520 rpm at pH values 5.0, 4.0, 3.0, respectively, and the corresponding critical shear rates (γ c) were calculated as 2.68 × 10 5 , 2.15 × 10 5 and 1.67 × 10 5 s-1 , respectively. Furthermore, shear induced dissociation and ultrafiltration (SIDU) were effectively applied to recover Sn 2+ and regenerate PMA. The SIDU is a promising technology for recovering tin and regenerating PMA. Compared with the traditional dissociation by acidification, SIDU avoids the use of acid and alkali, and it is in line with the idea of green chemistry.
