摘要：
The adsorption of phosphate ions from model solutions by a nanocomposite based on trivalent iron oxide-hydroxide and activated carbon (Fe-AC) is studied. The following factors affecting the adsorption of phosphate ions are investigated: the amount of adsorbent, the initial concentration of phosphate ions in a solution, and the contact time. The efficiency of phosphate ion removal increases with the adsorbent dose (from 2.5 to 10 g/L) at an initial phosphate ion concentration of 0.1 g/L. The adsorption is well described by Langmuir and Freundlich isotherms. The results show that the Fe-AC nanocomposite has a high adsorption potential for phosphate ions from aluminate solutions, which is confirmed by SEM/EDS analysis.
