properties in deionized water, and can be used as adsorbents for Cu(II) removal. The c-MWCNTMHs could be easily separated from water by a magnet and showed a high adsorption capacity for Cu(II). The adsorption of Cu(II) on the c-MWCNTMHs was quick and followed a pseudo-second-order model. The adsorption force between the c-MWCNTMHs and Cu(II) was of a chemical type and the saturated adsorbents can be regenerated at pH < 2.0. The magnetic Fe3O4 favored only the quick separation

As a novel adsorptive desulfurization method for the preparation of adsorbents, molecular imprinting technology is used to

Hydropropylcellulose (HPC)-modified multi-wall carbon nanotubes (HPC-MWCNTs) were prepared by physical adsorption of HPC on the surface of MWCNTs. The modification decreased the contact angle of water on HPC-MWCNTs and increased their water dispersion ability. However, HPC-MWCNTs dispersed in water were not stable and precipitated on the bottom of the container after 2 days as cylindrical bundles with a diameter of
