The subject research demonstrates the potential of unmodified magnetite nanoparticles as adsorptive media in applications such as remediating water sources contaminated with dissolved metals. Provided a sufficient quantity of adsorbent material, near-complete removal of contaminants can be attained through ion adsorption on magnetite nanoparticles. The use of magnetite for metal removal, followed by sequestration of the removed metal contaminants, has proven to be an effective and promising environmental remediation technique, as supported by statistical analysis. Magnetite possesses regenerative capabilities and can be desorbed and regenerated by mixing with solutions of varying pH levels. The study explored the potential reuse of the sequestering solution through repeated circulation of the strip solution. Due to its magnetic susceptibility, magnetite adsorbent facilitates solid-liquid separation. The data generated in this study contributes toward the development of a continuous ion exchange system for the treatment of streams contaminated with diluted concentrations of dissolved metal contaminants.
