Synthesis of bi-component ZrO2/Ag nanotube for heavy metal removal
This study was conducted to synthesize bi-component ZrO2/Ag nanotubes through anodization and photoreduction methods. The synthesized nanotubes were characterized and adsorption tests were carried out to evaluate its performance in removing heavy metal, lead (II). ZrO2 nanotubes were synthesized by anodizing zirconium foil in an electrolyte composed of glycerol, ammonium fluoride, formamide, and distilled water. The effect of anodizing time and the annealing process on the morphology of synthesized nanotubes were studied. Bi-component ZrO2/Ag nanotubes were prepared through photochemical reduction which silver precursor solution undergoes Ultraviolet (UV) irradiation in the presence of the active reducing agent. Larger pore diameter and longer length of synthesized nanotubes were formed at the longer anodizing time and the walls of nanotubes were smoother without annealing. The effect of the initial heavy metal concentration and contact time on the adsorption efficiency of synthesized nanotubes was evaluated using lead (II) as the heavy metal ions. Overall, the percentage removal of lead (II) increased with longer adsorption time and higher initial concentration of the lead (II) ions.
