Highly Efficient Removal of Cu(II) from Aqueous Solution by Using Graphene Oxide (2012, background): “…compared the adsorption capacity with literature value, the adsorption capacity here is 117.5 mgg−1 at the initial Cu(II) concentration of 250 mgL−1, which is much higher than that of carbon nanotubes and activated carbon in the literatures (Tofighy and Mohammadi 2011; Imamoglu and Tekir 2008).”
Multifunctional carbon nanotubes in water treatment: The present, past and future (2014, background): “• By controlling the target probes with various metal ions-specific DNAzymes (such as Cu2+, Mg2+ and Hg2+), the assay can be easily extended for use with other metal ions.”
