Al2O3/yttria-stabilized zirconia hollow-fiber membrane incorporated with iron oxide for Pb(II) removal
Removal by absorptive ceramic membranes can simultaneously absorb and separate metal ions from water. Alumina/yttria-stabilized zirconia (Al2O3/YSZ) hollow-fiber membranes, fabricated using phase inversion and sintering process, were deposited with iron oxide by an in-situ hydrothermal process.

| Summary: | Removal by absorptive ceramic membranes can simultaneously absorb and separate metal ions from water. Alumina/yttria-stabilized zirconia (Al2O3/YSZ) hollow-fiber membranes, fabricated using phase inversion and sintering process, were deposited with iron oxide by an in-situ hydrothermal process. The results showed that α-Fe2O3 was produced and incorporated across the membranes. A reduction in flux was recorded with the deposition of α-Fe2O3. However, it improved the adsorption capacity for heavy metal adsorption. The adsorption-separation test demonstrated that the optimized membrane is able to completely remove Pb(II) ions after two hours. |
