“…Due to development of modern technologies, the number of studies of ion transport in membranes has increased significantly in recent years. In turn, membrane technologies have found applications in important fields of science and industry, such as water treatment [1,2]; separation of mixtures and production of pure substances [3,4]; electrochemical energy conversion and storage devices [5,6]; chemical sensors and biosensors [7]; microfluidics and bioengineering [8,9]; etc. Despite the huge potential of membrane applications, there is a number of factors limiting their use, for example, separation capability (rejection), fouling, and flux decline.…”

4Grebenshchikov Institute of Silicate Chemistry (ISCh) RAS, 2 Adm. Makarova emb., St Petersburg 199155, Russia; anfimova-i@mail.ru (I.A.); antr2@yandex.ru (T.A.) Abstract: Nanocomposite membranes have been actively developed in the last decade. The involvement of nanostructures can improve the permeability, selectivity, and anti-fouling properties of a membrane for improved filtration processes. In this work, we propose a novel type of ion-selective Glass/Au composite membrane based on porous glass (PG), which combines the advantages of porous media and promising selective properties. The latter are achieved by depositing gold nanoparticles into the membrane pores by the laser-induced liquid phase chemical deposition technique. Inside the pores, gold nanoparticles with an average diameter 25 nm were formed, which was confirmed by optical and microscopic studies. To study the transport and selective properties of the PG/Au composite membrane, the potentiometric method was applied. The uniform potential model was used to determine the surface charge from the experimental data. It was found that the formation of gold nanoparticles inside membrane pores leads to an increase in the surface charge from −2.75 mC/m 2 to −5.42 mC/m 2 . The methods proposed in this work allow the creation of a whole family of composite materials based on porous glasses. In this case, conceptually, the synthesis of these materials will differ only in the selection of initial precursors.Nanocomposite membranes have been actively developed in the last decade [17]. The involvement of nanostructures can improve the permeability, selectivity, and anti-fouling properties of a membrane for improved filtration processes. One of the most promising approaches to producing such composite materials is the formation of nanoparticles inside the porous structure of a membrane. As with nanotechnology in general [18], there are two main methods [17] for the formation of nanoparticles inside the membranous pores: "top down"-bulk modification through blending (called mixed-matrix membranes) and "bottom up"-surface modification. In the fabrication of bulk-modified nanocomposite membranes, the nanoparticles are dispersed in a homogeneous polymeric precursor solution before the final formation process [19]. However, this method is difficult to use, for example, in the synthesis of inorganic solid membranes. The surface modification technique is the most convenient method in this case [11]. The surface modification technique deals with deposition of nanoparticles onto a membrane.Silicate (high silica) porous glasses (PGs) are channel-type nanostructures [20] with thermal, chemical and microbiological stability, in combination with controlled surface structural characteristics [21][22][23]. Special attention is worth paying to the PG application for the separation of liquid mixtures by reverse osmosis. This method has found application in water desalination, sanitary household water cleaning, water regeneration from vital function products in space, radioactive ...

“…Over the past two decades, the rapid socio-economic development around the globe has greatly influenced our personal apprehension for better hygiene and healthcare. The pharmaceutical sector has emerged as one of the main beneficiaries of such progress where uses of Pharmaceuticals and Personal Care Products (PPCPs) have been witnessed with improved accessibility and affordability [1]. By definition, pharmaceuticals are substances or their mixture intended for use in diagnosis, treatment and cure of diseases for human welfare [2].…”

“…They tend to persist in the environment over a longer period because of their recalcitrance nature and ultra low biodegradability. Numerous conventional wastewater treatment techniques for removing PhACs and EDCs have been reported such as activated sludge, microalgae, ozonation, wetlands and adsorption [1,2,15]. Unfortunately, most of the conventional treatments have failed to completely remove the pharmaceutical compounds from water and hence, some synergistic approaches would require achieving their full recovery from aquatic sources.…”

Background: The limitless presence of pharmaceutical contaminants in discharged wastewater has emerged as a threat to aquatic species and humans. Their presence in drinking water has although raised substantial concerns, very little is known about the fate and ecological impacts of these pollutants. As a result, these pollutants are inevitably introduced to our food chain at trace concentrations. Unfortunately, the conventional wastewater treatment techniques are unable to treat pharmaceuticals completely with practical limitations. The focus has now been shifted towards nanotechnology for the successful remediation of these persistent pollutants. Thus, the current review specifically focuses on providing readers brief yet sharp insights into applications of various nanomaterials for the removal of pharmaceutical contaminants. Methods: An exhaustive collection of bibliographic database was done with articles having high impact and citations in relevant research domains. An in-depth analysis of screened papers was done through standard tools. Studies were categorized according to the use of nanoscale materials as nano-adsorbents (graphene, carbon nanotubes), nanophotocatalysts (metal, metal oxide), nano-filtration, and ozonation for promising alternative technologies for the efficient removal of recalcitrant contaminants. Results: A total of 365 research articles were selected. The contemporary advancements in the field of nanomaterials for drinking and wastewater treatment have been thoroughly analyzed along with their future perspectives. Conclusion: The recommendations provided in this article will be useful to adopt novel strategies for on-site removal of the emerging contaminants in pharmaceutical effluents and related industries.

“…Adsorbents developed with favorable structures, morphologies, superior adsorption capacities, and ease of separation are a major focus of the current research [26,[52][53][54][55][56][57][58][59][60]. Recently, the development of nanotechnology has attracted considerable attention due to the remarkable potential of the nanoadsorbents for the selective and effective removal of ionic pollutants from aqueous solution when compared with the traditional adsorbents [13,33,[61][62][63][64][65][66]. The nanoadsorbents play a major role in the separation of heavy metal ions because they are effective sorbents due to their unique structural properties and specific adsorption tendency.…”

The indiscriminate disposal of non-biodegradable, heavy metal ionic pollutants from various sources, such as refineries, pulp industries, lead batteries, dyes, and other industrial effluents, into the aquatic environment is highly dangerous to the human health as well as to the environment. Among other heavy metals, lead (Pb(II)) ions are some of the most toxic pollutants generated from both anthropogenic and natural sources in very large amounts. Adsorption is the simplest, efficient and economic water decontamination technology. Hence, nanoadsorbents are a major focus of current research for the effective and selective removal of Pb(II) metal ions from aqueous solution. Nanoadsorbents based on graphene and its derivatives play a major role in the effective removal of toxic Pb(II) metal ions. This paper summarizes the applicability of graphene and functionalized graphene-based composite materials as Pb(II) ions adsorbent from aqueous solutions. In addition, the synthetic routes, adsorption process, conditions, as well as kinetic studies have been reviewed.
