“…Fullerenes have also been utilized in lithium ion batteries as anode and provide better efficiency with replacement of nondegradable metallic anodes, thereby proving to be beneficial in terms of efficiency and an environmentally friendly material. The physicochemical properties of fullerenes also make them suitable candidates for the extraction of different species from the aqueous media [59, 60]. Pickering et al designed water-soluble fullerene compounds and successfully applied them as sensitizer to produce reactive oxygen species (ROS) in water upon irradiation of visible and ultraviolet radiations.…”

“…It is believed that fullerenes adsorbed species by the penetration of adsorbates in the spaces/defects between the carbon nanoclusters, and in addition to the defects, lower aggregation tendency and large surface area make them useful nanomaterials to be applied for adsorption of heavy metal ions from water [61, 62]. Alekseeva et al conducted comparative studies of fullerene and nanocomposite-polystyrene film for the removal of Cu 2+ ions; they found that fullerenes showed better efficiency [60]. They have also found that fullerenes follow the Langmuir model of adsorption for Cu 2+ ions [60].…”

They have also found that fullerenes follow the Langmuir model of adsorption for Cu 2+ ions [60]. They established that the Cu 2+ removal efficiency of fullerenes is higher in the first case, and the equilibrium isotherm of the Cu 2+ adsorption on the fullerene fits the Langmuir model.…”

Nanotechnology is an advanced field of science having the ability to solve the variety of environmental challenges by controlling the size and shape of the materials at a nanoscale. Carbon nanomaterials are unique because of their nontoxic nature, high surface area, easier biodegradation, and particularly useful environmental remediation. Heavy metal contamination in water is a major problem and poses a great risk to human health. Carbon nanomaterials are getting more and more attention due to their superior physicochemical properties that can be exploited for advanced treatment of heavy metal-contaminated water. Carbon nanomaterials namely carbon nanotubes, fullerenes, graphene, graphene oxide, and activated carbon have great potential for removal of heavy metals from water because of their large surface area, nanoscale size, and availability of different functionalities and they are easier to be chemically modified and recycled. In this article, we have reviewed the recent advancements in the applications of these carbon nanomaterials in the treatment of heavy metal-contaminated water and have also highlighted their application in environmental remediation. Toxicological aspects of carbon-based nanomaterials have also been discussed.

“…Valcarcel et al [38] recognized that surface defects on fullerenes are the primary sites for adsorption when the contaminants enter the cage through spaces between the carbon nanoclusters. A study by Alekseeva et al [39] showed that Cu 2+ ions can be removed from water with an adsorption capacity of 14.6 mmol/g. Large-scale use of fullerenes is limited due to the prohibitive cost of fullerenes, Open Journal of Applied Sciences therefore small amounts of fullerenes are doped into adsorbents such as activated carbons.…”

The provision and demand for safe water continues to be a major aspect for governments worldwide as the population continues to grow accompanied by an increase in anthropogenic activities that contaminate water bodies. The common contaminants are the negatively charged ions such as sulfates, positive ions like heavy metals and organic molecules like dyes and phenols. Although, various methods exist for purification of wastewater, the adsorption process is a low cost method that uses readily available adsorbents. Activated carbon, although costly for developing countries, is still the most efficient adsorbent for a variety of substances. However, low cost adsorbents derived from biowaste have being actively explored in water purification. Photocatalytic nanostructured adsorbents not only play a bifunctional role in adsorbing contaminants but also are able to decompose organic pollutants in water using sunlight. The engineering of naturally abundant clay in most developing countries offers an even inexpensive way to clean-up wastewater.

“…Fullerenes have a hydrophobic character, high electron affinity, a high surface-to-volume ratio, and surface defects. Fullerenes have numerous applications, including in semiconductors, electronics, biomedical sciences, solar cells, sensors, cosmetics, artificial photosynthesis, and surface coatings [24,25]. The defects, lower aggregation tendency, and large surface area make fullerenes useful materials for the recovery of pollution from wastewater.…”

An Environmentally Friendly Method for Removing Hg(II), Pb(II), Cd(II) and Sn(II) Heavy Metals from Wastewater Using Novel Metal–Carbon-Based Composites

Rapid economic and industrial development and population growth have made water contamination a serious environmental problem and a major threat to public health worldwide. Heavy metals are extensively used in numerous industrial applications and are some of the most important environmental contaminants. The impacts of heavy metals on the health of humans, animals, and plants make their removal from wastewater and water resources an important and vital issue. In this study, a simple and environmentally friendly method is proposed for the synthesis of a ZnFe2O4-carbon nanotube (CNT) adsorbent material. SEM/EDX analysis and Fourier-transform infrared spectrophotometry (FTIR) are used to characterize the synthesized adsorbent material. We test the synthesized adsorbent material’s ability to recover four heavy metals (Hg(II), Pb(II), Cd(II) and Sn(II) ions) from an aqueous solution. We show that crushing fullerene CNTs with the ZnFe2O4 composite improves the adsorption properties of free fullerene CNTs towards the investigated heavy metal ions by 25%.
