| Popis: |
Zinc oxide nanotubes were synthesized by electrochemical deposition on zinc substrate using different Voltages (10, 20, 50) volts and different time periods of deposition (5, 10, 15, 20, 30, 45, 60) minutes. Zinc oxide nanotubes were characterized by atomic force microscope, optical microscope with a magnification (1000X), X-ray diffraction technique and thickness measuring device. Dealt with the studying of the effectiveness of the prepared nanotubes in the adsorption of ionic mercury and lead in them in water solutions using different temperature (15, 25, 35, 45, 55) ?C Also we calculate thermodynamic parameters (?S, ?H, ?G). |
