摘要：

Artificial zeolite was synthesized by hydrothermal method and activated by soaking in saturated aluminum sulfate aqueous solution. The activated zeolite was characterized by Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy(FT-IR); the fluoride adsorption on the zeolite from water was investigated; the effects of pH, temperature on F - ions adsorption was also discussed. Results showed that the zeolite had excellent fluoride adsorption capacity and rapid regeneration speed; the maximum fluoride adsorption capacity was 65.36mg/g and the time needed for the used adsorbent to be regenerated in saturated aluminum sulfate aqueous solution was only one minute. The adsorption mechanics were ascribed to hydrogen bonds attraction between hydroxyl groups and the fluoride ions in water.
