Chitosan/montmorillonite (CTS-MMT) composite beads were used as adsorbents for the removal of silver ion (Ag + ) from aqueous solution. Equilibrium adsorption was achieved within 150 min at 3% MMT of chitosan solution. The optimum pH value for Ag + removal was found to be 6-7. The maximum adsorbent dosage for Ag + removal was 5 g/L. Under above maximum conditions the Ag + removal was 95.7%. The maximum adsorption capacities of CTS and CTS-MMT composite beads as obtained from Langmuir isotherm were found to be 38.46 and 43.48 mg/g, respectively. The adsorption kinetic agrees well with the pseudo second order model. The Ag + desorption of CTS-MMT composite bead was 17.39% at pH=4. SEM/EDX images confirm that after adsorption the Ag + were dispersed onto the composite bead surface. The adsorption and desorption experiment demonstrated that the CTS-MMT composite beads can be used as an effective adsorbents for removal of Ag + from aqueous solution.

“…PPy–NPs with doped PO 4 3− could act as internal core templates for HA crystal nucleation and growth. In addition, PPy is also widely used as a chelation agent to adsorb metal ions through the amine group, such as Cr 4+ , Co 3+ , and Ag + , which suggests that PPy could be used as a stabilizing agent for Ag–NP formation in ED process.…”

“…The rules for polymer selection (as well as the concentration of the polymer solution) depend upon the intended applications for which the membrane is synthesized . The most well‐known polymers for the synthesis of membranes include: polysulfone, polyethersulfone, polyether ketone, polyphenylene oxide, polyphenylene sulfate, cellulose, nitrocellulose, cellulose acetate, polyethylene terephthalate, polyamide, polyimide, polycarbonate and polyethylene . By selecting a suitable solvent/non‐solvent, the coagulation temperature and the concentration of the polymer used in the preparation of membrane as well as addition of the some additives, the diameter of pores and distribution can be accustomed.…”

Ever since the discovery of graphene, its potential has been predicted for a number of applications in various fields such as electronics, sensors, environmental decontamination techniques, separations and biomedicine to name a few. Among various such fields, the research in graphene-based nanocomposites membranes is still in its infancy as there is not a significant research published in this field so far. However, interestingly this field is registering an exponentially upward trend recently. This review article provides a brief description of polymer nanocomposite membranes with graphene as one of the most indispensable components in the membranes. In this article, we describe in a systematic and comprehensive manner the most recent research published so far in the nanocomposite membranes with graphene and the most commonly used polymers namely the polysulfone and the cellulose derivatives. This article also describes the main applications of these polymeric membranes in the fuel cells and in water purification processes containing the current literature data as well as the authors' own research.
