چکیده:

In this study, the batch removal of zinc (Zn(II)) from aqueous solutions using titanate nanotubes (TNTs) as an adsorbent is investigated. TNTs are synthesized via a hydrothermal process with specific surface areas of 194.1 m2g-1 and pore volume of 0.21 cm3g-1. The influence of pH, adsorbent dosage, contact time and initial concentration of metal ions is studied. The maximum zinc adsorption occurs at pH 6, adsorbent dosage of 0.6 g/L and contact time of 90 min. It is recommended that further complimentary studies including equilibrium, kinetic and thermodynamic conduct to investigate the potential of TNTs for the removal of heavy metals from aqueous solution
