Here, we suggest that calcite coupling with magnetic NPs can be used to overcome the separation of NPs from treated water. Magnetic NPs (MNP) are pertinently significant due to their magnetic properties, small size, and the high surface-to-volume ratio [35], as well as their inert chemical behavior, less toxic nature, and ease of dispersion.
