A hybrid zirconium phytate (ZrxIP6) with porous surface was synthesized via the direct precipitation method. The as-prepared ZrxIP6 was characterized by SEM, EDS, FT-IR. The sample obtained from P/Zr = 3:1(mol/mol) indicated that a hybrid material might be formed through coordination of the zirconium ions with the –COPO3 groups in phytic acid molecules. An attempt to employ the hybrid ZrxIP6 as a sorbent in the removal of fluoride ions in metal-precoating wastewater was performed. The adsorption capacity qe and the residual F- ions concentration Ce using the ZrxIP6 (P/Zr = 3:1) as an adsorbent, were 1.21 mg.g-1 and 1.47 mg.L-1, respectively.
Key words: zirconium phytate / metal-precoating wastewater / hybrid material / adsorption
