Heavy metal ions removal from aqueous media by modified magnetic mesoporous silica MCM-48

- Modified magnetic mesoporous adsorbent was successfully synthesized.
- The obtained adsorbent was used to remove Pb(II), Cu(II), Cr(VI) and Cd(II).
- The adsorbent was presented a preferential binding capacity of Pb(II), Cu(II), Cr(VI) > Cd(II).
- The adsorbent was found to be suitable for reuse in successive adsorption-desorption cycles.
