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.
