Abstract
Here we show superparamagnetic iron oxide nanoparticles coated carbon nanotubes (CNTs) are easily synthesized, highly stable, biocompatible, with outstanding magnetic features. The effect of pH, contact time, contaminant concentration, and adsorbent amount on the adsorption process was measured.
