From the study of XPS and EDX, it was concluded that Fe(III) is impregnated on the natural stilbite ,zeolite, and the fluoride is adsorbed on the Fe(III)-stilbite ,zeolite,. And the result of desorption and regeneration showed that the exhausted Fe(III)-stilbite ,zeolite, can be regenerated using 1 M HCl as eluent and the regenerated samples still remain the good adsorptive performance.
