Abstract: Disclosed is a process, which is used to eliminate heavy metal cations from the aqueous media, and provides a better solution for the existing problems of the separation systems like low efficiency and high costs. The heavy metal cations selected for this purpose are cadmium, lead and copper. The separation system consists of a two stage process: In the first stage, the iron oxide nanoparticles are suspended in an aqueous medium contaminated with the heavy metal cations. In the second stage, the solution is brought into contact with a ferromagnetic matrix (or a paramagnetic matrix) magnetized by the application of an outside magnetic field. The heavy metal cations are deposited on the matrix under the imposed magnetic field. This two-stage process makes it possible to separate the heavy metal cations from the aqueous medium. The wire matrices are upon the completion of separation washed away by water or air current.
