“…Goethite (α-FeOOH), which already exists as a mineral in nature, is proven to be a competitive adsorbent towards heavy metals, thanks to its high adsorption efficiency, environmental safety and low cost [115]. Sun et al prepared nanoscale α-FeOOH by using different ferrous and ferric salts and employed it to remove uranium in water [116].…”

Removal of contaminants in wastewater, such as heavy metals, has become a severe problem in the world. Numerous technologies have been developed to deal with this problem. As an emerging technology, nanotechnology has been gaining increasing interest and many nanomaterials have been developed to remove heavy metals from polluted water, due to their excellent features resulting from the nanometer effect. In this work, novel nanomaterials, including carbon-based nanomaterials, zero-valent metal, metal-oxide based nanomaterials, and nanocomposites, and their applications for the removal of heavy metal ions from wastewater were systematically reviewed. Their efficiency, limitations, and advantages were compared and discussed. Furthermore, the promising perspective of nanomaterials in environmental applications was also discussed and potential directions for future work were suggested.

“…As a result, iron oxide nanoparticles could be efficiently employed to remove heavy metal from contaminated water and could thus be separated successfully from the systems [127,175,257]. Goethite (α-FeOOH) is studied a lot where it is manifested that they are competitive adsorbent of heavy metals owing to their cost-effectiveness, good adsorption capability and environmental friendliness [149]. Goethite was reported to be synthesized from ferrous and ferric salts to remove uranium from water [250].…”

Water comprises an integral component of human life and its accessibility is essential for all life in the entire planet. Due to climate changes and other manmade activities, the world is facing shortage of drinking water. There are a number of pollutants present in the water such as gases, chemicals and heavy metals. Therefore, it is imperative to decontaminate water for a healthy planet. There are numerous problems and challenges of wastewater treatment. For better ecological and health issues some measures are required to take in advance to avert possible evil or to secure good results. Metal-based nanomaterials have found exceptional use in the decontamination purpose due to their nature which arises from nanosize, such as better adsorption and catalytic activity. Metal-based nanomaterials can productively remove different contaminants from water and they have been effectively applied in decontamination of water. Due to having larger surface area and having ability to work at low concentration these metal-based nanomaterials are very efficient in wastewater treatment. Nanoengineered nanoparticles impart a promising and effective treatment method to wastewater and thus can be adapted simply. Modern techniques for treatment of wastewater must be cost-effective and accessible for commercial use. In this chapter, we outline the role of metal-based nanoparticles and nanocomposites applied in water decontamination. Moreover, we discuss the advantages, disadvantages, shortcomings and future prospects associated with these nanomaterials.

“…The adsorption technique is simple, cost-friendly and non-toxic [14][15][16][17]. Thereupon, useful and easy-to-prepare adsorbents are needed to developed for the heavy metal removal [18] such as iron oxide [19,20], activated carbon [21], kaolinite [22] and zeolite [23]. On the contrary, these materials have some drawbacks such as aggregation, low adsorption capacity and poor mechanical strength resulting in low yields [24].…”

T he increasing number of factories with the heavy metal wastes, especially lead, such as a battery, dye, and fertilizer manufacturing, etc. [1], in consequence of the fast developments of agricultural and industrial fields, threaten the ecological environment and human health. The heavy metal ions cannot be degraded, and resulted in an accumulation in the living organism tissues [2]. The lead limits in drinking water allowed by the World Health Organization is 10 μg/L [3]. Moreover, even very little concentration of lead can cause severe consequences for living things including humans [4]. Because its high affinity to enzymes having thiol (-SH) and phosphate ions (PO 4 3-), ligands and biomolecules inhibiting the haem biosynthesis, Pb 2+ ions are very hazardous for the permeability of cell membranes in kidney, liver, and brain and likewise toxic for nervous and reproduction system, resulting in abortion, dead and neonatal birth, mental retardation [5, 6], etc. Additionally, it may form complexes with the oxogroups of enzymes which are very active in porphyrin metabolism and haemoglobin synthesis [7]. Besides the potential neurological and carcinogenic effects of lead, it may cause cognitive and physical retardation in child development, especially in the interval of 0-7 age [8]. Lead has been classified as a carcinogenic
