Water is an essential part of life and its availability is important for all living creatures. On the other side, the world is suffering from a major problem of drinking water. There are several gases, microorganisms and other toxins (chemicals and heavy metals) added into water during rain, flowing water, etc. which is responsible for water pollution. This review article describes various applications of nanomaterial in removing different types of impurities from polluted water. There are various kinds of nanomaterials, which carried huge potential to treat polluted water (containing metal toxin substance, different organic and inorganic impurities) very effectively due to their unique properties like greater surface area, able to work at low concentration, etc. The nanostructured catalytic membranes, nanosorbents and nanophotocatalyst based approaches to remove pollutants from wastewater are eco-friendly and efficient, but they require more energy, more investment in order to purify the wastewater. There are many challenges and issues of wastewater treatment. Some precautions are also required to keep away from ecological and health issues. New modern equipment for wastewater treatment should be flexible, low cost and efficient for the commercialization purpose.

“…It was apparent that the G/CNT film strongly enhanced the oxidation of OLA, which remarkably raised the response signal of OLA. The O-O bonding occurs between C=C double bonds or benzene rings of adsorbed OLA on G/CNT surface 41 and there are four proposed adsorption sites of OLA for G/CNT bundles including outermost surface, interstitial channels, inner cavities and grooves. 42…”

An electrochemical sensor based on a three-dimensional (3D) graphene/carbon nanotube (G/CNT) hybrid was developed for the sensitive detection of olaquindox (OLA). 3D G/CNT hybrid through covalent C-C bonding was fabricated by one-step synthesis using catalytic chemical vapor deposition. To construct the base of the sensor, a novel composite was fabricated by a functionalized 3D G/CNT with poly-(dimethy diallyl ammonium chloride) and Nafion via simple grind and ultrasonication dispersion methods. The electrochemical determination of OLA exhibited an oxidation peak at −0.685 V with a higher current response. Due to the effective surface area and active sites, a good linear relationship was observed between the OLA concentration and peak current over the range of 1.5 × 10 −6 -2.7 × 10 −3 mg mL −1 with a detection limit of 6.12 × 10 −8 mg mL −1 (3σ). The proposed electrochemical sensor was used to detect OLA in swine samples at a recovery ranging from 97.78% to 104.25%, which exhibits a broader prospect to supervise animal products and a high potential for food security applications.

“…[12][13][14][15] For the adsorption method, the focus of the research is to obtain adsorptive materials with excellent properties and easy preparation process. Therefore, some advanced carbon materials with these adsorptive characteristics, such as graphene, [16][17][18][19] carbon nanotubes [20,21] and carbon nanofibers, [22,23] that have been deeply investigated have achieved quite gratifying results. [24] Recently, graphitic carbon nitride (g-C 3 N 4 ), a novel two-dimensional (2D) graphite-like stratified material, has obtained intense interest as a non-metal polymer semiconductor photocatalyst due to its excellent chemical stability, thermal stability, optical properties and outstanding potential for energy conversion and storage.…”

A novel g‐C3N4/MnO2 composite was prepared by in situ deposition of MnO2 on graphitic carbon nitride (g‐C3N4) nanosheets, and its adsorption properties were evaluated for removal of Pb (II) in aqueous. Fourier transform‐infrared, spectrometer scanning electron microscopy and transmission electron microscopy characterization showed the g‐C3N4/MnO2 composite had a two‐dimensional/two‐dimensional (2D/2D) structure with ample active sites. The Brunauer–Emmett–Teller specific surface area of g‐C3N4/MnO2 composites (234.9 m2/g) was 13.5 times larger than that of g‐C3N4 (17.37 m2/g), providing better conditions for adsorption. The adsorption kinetic data were better fitted with the pseudo‐second‐order model. The Langmuir model was more suitable for describing the experimental equilibrium data of g‐C3N4/MnO2, and the maximum adsorption capacity was 204.1 mg/g for Pb (II). The adsorption of g‐C3N4/MnO2 composite for Pb (II) was an endothermic and spontaneous process, and reached adsorption equilibrium rapidly within initial 150 min. This composite was an excellent adsorbent because of its higher adsorption capacity and facile preparation progress.
