摘要: In this study, the uptake equilibria and mechanisms of heavy metal ions Pb(II), Cu(II), Cd(II), Zn(II) on microporous titanosilicate ETS-10 were attempted in absence presence background electrolyte NaNO3 different concentrations batch systems. The properties metals found to be related zeta (ζ) potential profile characteristics terms their hydrolysis, hydrated ionic radii, hydration energies. strength pH observed have a significant impact equilibrium capacity due competition Na+ proton variation surface electrochemical adsorbent. desorption data counterions indicated that ion exchange is mainly responsible for Zn(II), while other such as adsorption complexation may cooperative addition case Pb(II) solid.
