Sepiolite is a natural mineral with high efficiency for phosphate removal but it can not be used as filter media due to its small particle size. Therefore, we suggested the used of sepiolite by inoculating it into cellulose acetate polymer beads. The polymer solution was prepared by dissolving cellulose acetate (CA) to acetate with their ratio 15:85 and 15% of poly ethylene glycol was added to the polymer solution. Experimental results show that the optimum amount of sepiolite inoculation was 30% (30_SPL-CA) and its adsorption amount of phosphate was 17.74 mg/g. Langmuir model was more suitable for describing phosphate adsorption onto 30_SPL-CA than the Freundlich model . As the temperature increased, phosphate adsorption was increased, indicating that phosphate adsorption was endothermic reaction. Phosphate removal efficiency was decreased with increasing pH. In column experiment, the breakthrough of phosphate was not observed for 60 hours in the column packed with 30_SPL-CA. The results of this study suggest that 30_SPL-CA bead can be used as an efficient water treatment material for phosphate removal.
