  • Simultaneous and synergistic effect of heavy metal

    Adsorption efficiency for Cu(II) ions was 50% but differed among the heavy metal ions ((Pb(II) gt; Cd(II) gt; Cu(II) gt; Zn(II)). Adsorption was inversely related to hydration energy, as reported by Liu et al. (2013) for adsorption of Pb, Cd and Cu on titanate nanotubes. Thus removal of heavy metal ions depends upon both the properties of the ions
