Abstract

Magnetic nanoparticles are very effective in removing heavy metals from wastewater that can be produced by adding to mineral adsorbents, a modified adsorbent with high adsorption properties. The addition of magnetite nanoparticles to bentonite increases the cationic adsorption power of bentonite. In this paper, the adsorption of cobalt ions on metal ions is investigated using synthesized magnetite bentonite nano-absorbent (SMB) (30-40 nm). First, The nano-absorbents were produced by co-precipitation and analyzed by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), and Fourier Transform InfraRed (FT-IR) spectroscopy, then used as adsorbent. The experiments were designed and evaluated by design expert software. Optimal conditions were obtained by CCD model for metal ion adsorption (removal). The optimum amount of adsorption of Co 2+ ion from the solution was 95%.
