چکیده:

Titanate nanotubes (TNTs) are successfully synthesized via a hydrothermal process. These nanotubes with specific surface areas of 194.1 m2g-1 and pore volume of 0.21 cm3g-1 are employed to remove heavy metal ions via adsorption method. TNTs can be synthesised via changing NaOH concentration, temperature, time of reaction and the pH value of washing solutions. In this study, TNTs are synthesized with NaOH concentration of 10 M at the temperature of 130 °C for 96 h and washed with double distiled water and HCl solution of 0.1 M. The characterization of TNTs are investigated by SEM, XRD, and BET analyses.
