studies indicated that Zn(II) was removed as neutral and anionic chloro-complexes according to the ion pair and ionexchange mechanism. Adsorption isotherms were also studied to understand the mechanism of the removal and used models confirmed that the binding of Zn(II) was mainly controlled by chemisorption, with the maximum sorption capacity 210 mg Zn(II) per gram of the resin. Zn(II) can also be easily
for potential novel sorbents, mesoporous ionic liquid-functionalized silicas were synthesized and tested for the removal of Pb(II) from aqueous solutions. The successful synthesis of the adsorbents was proved by nuclear magnetic resonance (29Si and 13C NMR), Fourier transform infrared spectroscopy (FTIR), and elemental analysis. The structural and textural properties were determined using scanning electron
