“…In recent years, raw clays such as montmorillonite, vermiculite, kaolinite and bentonite, and especially their modified organoclays with cationic surfactants, have been widely used as efficient adsorbents of heavy metal ions or organic pollutants . Some studies have shown that the adsorption capacity of organo‐montmorillonite modified with quaternary ammonium cationic surfactants on pollutants is greatly improved compared with the original clay .…”

BACKGROUND: Copper is a heavy metal that is widely available in nature and has attracted people's attention because of its toxicity and difficult biodegradability. Using modified montmorillonite to adsorb copper ions (Cu 2+ ) was widely adopted because of its simple operation, high efficiency, and easy availability. RESULTS: Na-montmorillonite (Na-Mt) was modified through a Gemini surfactant (containing four ammonium cations) to explore the adsorption capacity for Cu 2+ in aqueous media. The resulting product is called G-Mt. FT-IR XRDBET results indicated that Gemini surfactant has significantly intercalated into the montmorillonite interlayers. The results ofbatch adsorption experiments presented that the amount of adsorbed (qe) depend on pH value and qe (G-Mt) can reach to 29.30 mg/g, which was greater than that of Na-Mt (25.30 mg/g) when pH is 6.0 and initial Cu 2+ concentration is 75 mg/L. The experimental data matched well with Langmuir isotherm. The thermodynamic analysis implied that adsorption of Cu 2+ was endothermic and a spontaneous process. Molecular dynamics (MD) models were carried out to investigate the microstructure and kinetic information of Gemini cations in the interlayer of G-Mt. The results elucidated that the distribution and interaction characteristic of ammonium cations of Gemini surfactant including four ammonium cations were completely different from that of the quaternary ammonium salts containing asingle ammonium cation. CONCLUSION: Generally, considering the comprehensive performances, polyamine Gemini surfactant to modify montmorillonite can improve its ability to adsorb Cu 2+ . The micro environment in the interlayer space and adsorption properties of G-Mt on Cu 2+ , which will improve the potential utilization of G-Mt in soil remediation or wastewater treatment. Y Chu et al.with the original clay. 10,11 Luo et al. 12 used butane-1,4-bis(dodecyl dimethyl ammonium bromide) (gBDDA)-and dodecyl trimethyl ammonium bromide (DTMA)-modified montmorillonite (Mt) to adsorb chromate and phenol. The study revealed that using a Gemini surfactant such as gBDDA to modify Mt would significantly reduce or even have the potential to eradicate the secondary pollution by modifier release during the adsorption process. Li et al. 13 used propyl bis(hexadecyl dimethyl ammonium) chloride (16-3-16)-modified calcium montmorillonite (Ca-Mt) to obtain organo-montmorillonite (G-Mt). The material was used to adsorb a class of emerging contaminants (ECs) such as 1-hydroxybenzotriazole (HOBT), 1H-benzotriazole (BTA) and 5-methyl-1H-benzotriazole (TTA) from wastewater. The maximum adsorption capacities at equilibrium were 25.93, 18.31 and 16.24 mg g −1 for HOBT, BTA and TTA respectively, greater than that of Ca-Mt.Recently, dimeric Gemini surfactant-modified organo-Mts have been of interest to researchers for their applications for adsorbing organic pollutants. 14,15 These dimeric Gemini surfactants generally contain two hydrophilic head groups and two hydrophobic chains linked by a spacer and are expected to ex...

Polymeric materials have been remarkably associated with our daily life. The hydrophilic/hydrophobic biopolymer systems have gained importance in the last few years, because of the environmental pollution of nonbiodegradable synthetic plastics. Recently, biopolymers with functional groups have been directly used for the fabrication of adsorptive membranes in order to avoid the undesirable morphology change of the membranes during the surface modifications. Compared with other modification technologies or a synthesis of totally new materials, biopolymer blending has several advantages like simplicity, reproducibility, and commercial feasibility. The valuable part of blending of biopolymers can be used for the preparation of new materials with improved physicochemical and mechanical properties. The objective of this work is the development of biomembranes based on a mixture of three biopolymers, that is, alginate (AL), chitosan (CS), and polylactic acid (PLA). Physical characterizations of the elaborated biopolymeric membranes are carried out by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and contact angle measurements. The SEM results show that the synthesized membranes exhibited homogeneous dense microstructures. The second objective of this paper is to evaluate the importance of these biopolymers in removing lead which is considered as toxic metal. In fact, all synthesized membranes are applied to the treatment of wastewater to eliminate heavy metals principally

“…Thus, it has been considered as an essential field of research for several decades. [14][15][16][17][18][19][20] The major component of such polymeric membranes has been cellulose, [21][22][23][24][25][26][27][28] which is the most abundant, environmental friendly and sustainable natural biopolymer, [29] suggesting the continuous efforts of scientists to exploit functional materials from cellulose. Polymeric membranes, which utilize cellulose triacetate (CTA), polysulfone (PSu), polyethersulfone (PES), and polyvinylidene fluoride (PVDF) are the dominant membranes used for metal recovery.…”

This paper reports on the synthesis of a novel class of polymer inclusion membranes prepared by thermally‐induced phase separation using a mixture of two polymers: polyvinylidene fluoride (PVDF) and cellulose triacetate (CTA) plasticized by dioctylphtalate (DOP) and doped with organo–phosphoric compound: trioctylphosphine oxide noted (TOPO) as mobile carrier. The membranes (polymers − plasticizer − carrier) are characterized using physical techniques as well as Fourier transform infrared (FTIR) and thermo‐gravimetric analysis (TGA). All synthesized polymeric membranes are applied for investigation to the facilitated transport of Pb2+ and Cd2+ ions from aqueous nitrate source phase. All membranes are thermally stable up to nearly 178 °C. A study of the transport across a polymer inclusion membrane has shown that the lead transport efficiency is increased using TOPO as carrier. This study represents an interesting approach in the treatment of hydrometallurgical solutions using the TOPO neutral carrier mediated transport.
