were studied by the experiment. The mechanism on modifying adsorbent was preliminarily discussed. The main technical parameters were determined on adsorption treatment of high fluoride drinking water using modified artificial zeolite. The key factors of affecting the F- removal efficiency were revealed. The study provided scientific basis for the development of efficient and practical small set for treating high-fluoride drinking water. Results show that F- removal performance of artificial zeolite modified by NH
