Synthesis, Characterization of Titanium Dioxide Nanotubes, and their Application as an Adsorbent for Removing of Heavy Elements

The nanotubes were prepared by anodizing method. anodization process was carried out using 60 volts between two titanium plates as electrodes, leaving a distance the electrodes 6.5 cm. electrolyte contains (0.5 w/w NH4F, 2 H2O, 5 ethylene glycol). A scanning electron microscope (SEM) used to examine surface morphology of dioxide (TiO2). SEM image shows that tubes are in range (80-90 nm) diameter. (TiO2) effective adsorbents for water treatment. Titanium have been adsorption heavy metals polluting such lead and cadmium. study showed longer had higher rates, rate reached 94.11% cadmium 29.81%. Estimate concentration elements before after examined flame atomic absorption device.
