MWCNTs-Fe3O4 nanocomposite for Hg(II) high adsorption efficiency

Magnetic carbon nanotubes composite (MWCNTs-Fe3O4) was successfully prepared and characterized using different techniques. MWCNTs-Fe3O4 displays entangled network of oxidized MWCNTs attached with Fe3O4 clusters with specific surface area of 92 m2 g−1. The adsorption performance of as prepared compos...
