“…In the modern era, the environment has been significantly impacted by the release of heavy metals such as chromium (Cr), lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), copper (Cu), and selenium (Se) from industries such as metal finishing, electroplating, textiles, batteries, glass, mining, refining ores, pesticides, paper, fertilizer, tanneries, and so on (Godwin et al., 2019; Karthik et al., 2022). Researchers are using a variety of approaches, including reverse‐osmosis, ion‐exchange, adsorption, ultrafiltration, membrane technology, and so on, to eliminate these toxic metals from industrial effluents (Alalwan et al., 2020; Asaithambi et al., 2021; Rajesh Banu et al., 2021). Due to its less expensive, adaptable, and extremely straightforward procedure, numerous studies are currently focusing on the utilization of SSB as an adsorbent for the elimination of heavy metals from industrial effluent.…”

The generation of sewage wastewater is unavoidable due to the continual increase in the global population that paves the way to appropriate disposal management. Sewage wastewater treatment and consequent generation of sewage sludge (SS) are well connected with global environmental issues. Upon risk assessment on different SS disposal methods, converting SS into biochar, that is, sewage sludge biochar, can be recommendable management. It is well‐proven for excellent positive impacts, such as nutrient enhancement, and healthier plant growth, and mitigates the emissions of greenhouse gases while amending with agricultural soil. However, the outcome features of SSB significantly vary with pyrolysis temperature and its elemental constituents. In addition, many studies revealed that the process temperature is key to responsible for the desirable properties and functioning of SSB. In this context, many countries support to the development of a futuristic strategy for SS management toward producing SSB and its utilization in agriculture. This review compiles studies into SSB's ability to promote a sustainable effect on the total worldwide output volume. Furthermore, the generation of SSB is also analyzed from a socioeconomic standpoint in relation to other common SS disposal management strategies.

“…Their results showed that the removal efficiency from coal mine wastewater was about 85 % of phosphate, 76 % of sulfate, 96 % BOD, and 93 % of COD. From domestic wastewater, the removal efficiency was about 80 % for phosphate, 89 % for total nitrogen, 63 % for nitrate, 64 % for sulfate, 96 % for BOD, and 72 % for COD (Rajesh Banu et al, 2021). The removal efficiency from the Mzingazi River was about 92 % of phosphate, 52 % of total nitrogen, 89 % of BOD, and 92 % of COD.…”

The synthesis, characterization, and applications of nanoparticles (NPs) for environmental remediation are reviewed in this review article. An overview of several synthesis techniques—such as precipitation, thermal decomposition, and hydrothermal synthesis—that allow the creation of NPs with precise size, shape, and magnetic properties is given in this work. It also explores methods for characterizing NPs, which are essential for understanding their chemical, magnetic, and physical properties. These methods include vibrating sample magnet magnetometry (VSM), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Most reviews highlight the application of NPs in environmental remediation, emphasizing their efficiency in the adsorption and removal of organic pollutants, heavy metals, and dyes from contaminated water. Case studies demonstrate the use of NPs in real-world ecological remediation situations, highlighting its promise as an environmentally beneficial and long-term method of remediation of soil and water. The review discusses NP-based addresses and prospective future initiatives, such as the need for scalable synthesis methodologies, the development of more advanced functionalization strategies to target specific pollutants and environmental impact assessments.

“…While some metals aid in organisms’ metabolism, consuming too much of them might lead to certain health complications . However, due to their deadly nature and high resistance, these various contaminants have had significant detrimental impacts on the ecosystem even at low concentrations . The following shows the levels of toxicity of the heavy metals when compared: Se < Zn < Cu < Ba < Cr < Hg < As. , India’s population is predicted to reach 1.51 billion by 2030 due to high population growth, which would contribute to severe water constraints.…”

In recent years, organic and inorganic contaminants in wastewater (heavy metals, halides, nutrients, dyes, and pathogenrelated water pollution) have become a major global problem. There were initially fewer toxins, but as a result of fast industrialization and other human activities, they have rapidly risen. In addition to producing a host of health problems and organ system failure in people, these toxins have had a disastrous effect on the ecological balance of plants, animals, and even microbes. On the basis of nanotechnology, several methods for decontaminating water that use nanoadsorbents and/or photocatalysts are being researched. Due to their improved physical and chemical characteristics, several research studies have focused on the elimination of organic and inorganic pollutants using ferritesupported nanocomposite polymers as possible affordable substitutes for currently employed materials. In this review, the toxicity of heavy metals and the different adsorption capabilities of metal-doped ferrites, which are employed to detect the pollutants in wastewater, are discussed in detail. Also, it provides various synthesis methods to produce ferrite-supported polymer-based nanocomposites and a current review of them with a special emphasis on their exceptional ability to remove organic and inorganic pollutants from wastewater. As a result, ferrite-supported polymer-based nanocomposites, which are also less expensive and swellable, can act as effective adsorbents for the removal of both organic and inorganic pollutants. It has outstanding performance for sizes between 10 and 30 nm.
