| Abstract: | A ZrO 2 based adsorbent, the waste resin from thermo eletric plant loaded with ZrO 2 was developed, and its adsorption and desorption performance for fluoride removal were evaluated. Experimental results show that the proper concentration of zirconium is 0 5 mol/L. The optimum pH for adsorption and desorption are about 4 and 12 respectively. The adsorption of fluoride follows Langmuir isotherm in the tested range of fluoride concentration and q e was 5 000 mg/L calculated by Langmuir isotherm. The adsorbent was applied for the removal of fluoride form synthetic wastewater of thermo eletric plant, and similar fluoride removal performance was obtained. |
