Abstract
Synthetic ZrO2 · nH2O was used for phosphate removal from aqueous solution. The optimum adsorbent dose obtained for phosphate adsorption on to hydrous zirconium oxide was 0.1 g. The kinetic process was described very well by a pseudo-second-order rate model. The phosphate adsorption tended to increase with the decrease in pH. The adsorption capacity increased from 61 to 66 mg g-1 when the temperature was increased from 298 to 338 K. A phosphate desorption of approximately 74% was obtained using water at pH 12. © 2012 Taylor & Francis.
