Abstract A reliable access to potable and safe drinking water represents one of the biggest global challenges of the 21st century. Among several globally pervasive and emerging reasons behind the water quality deterioration, accumulation of heavy metals in the aquatic environment has been considered to be one of the top notch causes. In a quest to explore sustainable solution for combating this problem, recently attempts have been directed toward the effective integration of nanotechnology with the superior adsorption technology. Within this perspective, it is important to mention that researchers have developed superior nanoadsorbents that are magnetically retrievable and have shown great prospects of effectively removing while simultaneously recovering heavy metals from different charged wastewater. This chapter provides an extensive overview on the different types of magnetic nanoadsorbents designed by the scientific fraternity to date for heavy metal remediation. In order to enlighten the readers about the large-scale industrial applicability of these materials, there is a special emphasis on the design of novel reactors for the cyclic recovery of these metals. In addition, a critical investigation on the applicability of developed nanomaterials is attempted, considering the economic viability, environmental safety, and sustainability of the proposed processes.
