Amorphous Zirconium Dioxide as a Potential Sorbent for Selective Removal of Phosphates in Aqueous

Abstract:

In the present study, we fabricated the amorphous zirconium oxides by the classic sol-gel precipitation methods. SEM analysis proved that the prepared ZrO₂ particles are micrometer scales and XRD further illustrated its amorphous nature. The effects of solution pH on adsorption suggests the phosphate retention onto ZrO₂ was a pH-dependent process and the optimum pH values between 4.5-8.0; competition tests also demonstrated its excellent selectivity by comparing D201 resin in presence of common anions at high levels. All the results proved that ZrO₂ is a promising adsorbent for P(V) sequestration.
