“…This method helps in the oxidative elimination of pollutants such as organic, microbes and micropollutants such as dyes, antibiotics, etc. (Quek et al ., 2018; Wang et al ., 2018; Zhang et al, 2018b). For example, a study by Zhang et al ., made use of photocatalytic activity of nanocomposite material to degrade the refractory organic contaminations from water.…”

“…It was observed that these nanocomposites completely degraded the pollutants within 24 hours of solar irradiation. The high mineralisation degree indicates that the potential hazard to the environment has been considerably reduced after degradation (Zhang et al ., 2018b). Another study by Wang et al ., demonstrated the degradation of dyes such as rhodamine B and methyl orange by iodine and carbon codoped TiO 2 photocatalyst.…”

Water contamination is a global challenge impacting both the environment and human health with significant economic and social costs. The growing scarcity of usable water resources requires effective treatment of wastewater. In this context, developing cheaper, safer and more efficient wastewater treatment technologies are the need of the hour. One promising approach that several studies have reported success has been the usage of nanomaterials in water and waste water management. The rapid progress of research in nanomaterial sciences has shown their growing potential; however, there has not been a great amount of information available on their implementation. This review focuses on developments in nanotechnology that hold strong potential for wastewater treatment. The review covers key techniques in nanomaterial‐based water treatments including adsorption, filtration and photocatalysis with recent examples showing how to improve their properties and efficiencies according to the need.

“…The first-order regime has the highest R 2 and the lowest χ 2 values, indicating that this kinetics model best fits the experimental data ( Zhang et al, 2011 , Ahmed et al, 2020 ). The kinetics of the photocatalytic removal of lopinavir and ritonavir in model and real treated wastewaters by the synthesized multiphase photocatalysts followed a pseudo-first-order regime ( Ahmed and Emam, 2019 , Zhang et al, 2019 ).…”

The use of antiviral drugs has surged as a result of the COVID-19 pandemic, resulting in higher concentrations of these pharmaceuticals in wastewater. The degradation efficiency of antiviral drugs in wastewater treatment plants has been reported to be too low due to their hydrophilic nature, and an additional procedure is usually necessary to degrade them completely. Photocatalysis is regarded as one of the most effective processes to degrade antiviral drugs. The present study aims at synthesizing multiphase photocatalysts by a simple calcination of industrial waste from ammonium molybdate production ( WU photocatalysts) and its combination with WO 3 ( WW photocatalysts). The X-ray diffraction (XRD) results confirm that the presence of multiple crystalline phases in the synthesized photocatalysts. UV-Vis diffuse reflectance spectra reveal that the synthesized multiphase photocatalysts absorb visible light up to 620 nm. Effects of calcination temperature of industrial waste (550-950°C) and WO 3 content (0-100%) on photocatalytic activity of multiphase photocatalysts ( WU and WW ) for efficient removal of SARS-CoV-2 antiviral drugs (lopinavir and ritonavir) in model and real wastewaters are studied. The highest k 1 value is observed for the photocatalytic removal of ritonavir from model wastewater using WW4 (35.64×10 –2 min –1 ). The multiphase photocatalysts exhibit 95% efficiency in the photocatalytic removal of ritonavir within 15 of visible light irradiation. In contrast, 60 min of visible light irradiation is necessary to achieve 95% efficiency in the photocatalytic removal of lopinavir. The ecotoxicity test using zebrafish ( Danio rerio ) embryos shows no toxicity for photocatalytically treated ritonavir-containing wastewater, and the contrary trend is observed for photocatalytically treated lopinavir-containing wastewater. The synthesized multiphase photocatalysts can be tested and applied for efficient degradation of other SARS-CoV-2 antiviral drugs in wastewater in the future.

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.
