“…Table 5 compares the adsorption capacities of the adsorbent obtained in this work with different adsorbents previously used for removal of Ni (II). It can be seen from Table 5 that the adsorption capacities of the synthesized adsorbent for Ni (II) are much higher than that of many other previously reported adsorbents, indicating that the prepared adsorbent has great potential application in Ni (II) removal from aqueous solution [63][64][65][66][67][68][69][70][71][72][73][74].…”

“…However, by increasing the amount of SDS, adsorption increased remarkably by the gradual formation of SDS aggregates on the surface of Fe 3 O 4 NPs. In this case, the surfactant was added to the magnetite NPs aqueous dispersion in the presence of heavy metals ions [78]. SDS-coated Fe 3 O 4 -NPs were prepared and applied for pre-concentration and determination of Hg 2+ ions from water samples.…”

Nanosized magnetite has emerged as an adsorbent of pollutants in water remediation. Nanoadsorbents include magnetic iron oxide and its modifiers/ stabilizers, such as carbon, silica, clay, organic moieties (polymers, aminoacids, and fatty acids) and other inorganic oxides. This review is focused on the recent developments on the synthesis and use of magnetic nanoparticles and nanocomposites in the treatment of contaminated water. The emphasis is on the influence of the iron oxide modifiers on some properties of interest such as size, BET area, and magnetization. The characteristics of these nanomaterials are related to their ability to eliminate heavy metal ions and dyes from wastewater. Comparative analysis of the actual literature was performed aiming to present the magnetic material, its preparation methodology and performance in the elimination of the selected pollutants. Vast information has been properly summarized according to the materials, their properties and preferential affinity for selected contaminants. The mechanisms governing nanomaterial's formation as well as the interactions with heavy metals and dyes have been carefully analyzed and associated to their efficiency.

“…The resulting surfactant/polyelectrolyte complexes form aggregate structures from the nano to micro scales. The structure and phase behavior of the resulting complexes can influence different parameters, such as charge density, molecular weight, hydrophobicity, concentration of the complex, and salinity of the wastewater, as well as the structure, polar head charge, hydrophobicity, and surfactant concentration …”

[28][29][30][31][32][33][34][35][36][37][38][39][40][41] The objective of the present study is to improve the coagulationflocculation effectiveness of a partially hydrolyzed polyacrylamide, p (AAm-co-AA), for treating industrial wastewater, by simply adding a surfactant or an organic cation (TAB). Produced water (PW) was studied.…”

The flocculation activity of commercially available anionic poly (acrylamide‐co‐acrylic acid), p (AAm‐co‐AA) has been significantly improved, without any inorganic coagulant aid. The effect of three types of surfactants, anionic sodium lauryl ether sulfate (SLES) (Palm Epimen), nonionic cocamide DEA, zwitterionic amphoteric Amphotensid B5, and one organic cation, trimethylammonium bromide (TAB) on coagulation/flocculation performance have been investigated. The performance has been analysed in terms of turbidity, total suspended solid (TSS), total iron (TI) content, and BTEX for treating two kinds of industrial wastewater, produced water (PW) and starch water. We have shown that adding a small amount of each of the studied surfactants, and especially cationic TAB, significantly increases the coagulation/flocculation performance without modifying pH levels. A combination of low dosage of flocculant (310 ppb) and TAB (310 ppb), after 5 minutes, presented 88%, 81%, and 62% reduction in turbidity, TSS, and TI content, respectively, whereas by using 5 ppm of flocculant alone (16 times more), only 76%, 75%, and 43% removal was obtained. The results reveal that TAB performs as an efficient coagulant booster. Compared with regular inorganic coagulants, it is more cost‐effective, reduces the consumption of treatment chemicals, and the pH‐dependency of contaminants removal.
