AbstractA technology for the granulation of fe-al-ce nano-adsorbent (fe-al-ce) in a fluidized bed was developed. the coating reagent, a mixture of fe-al-ce and a polymer latex, was sprayed onto sand in a fluidized bed. the granule morphology, coating layer thickness, granule stability in water and adsorption capacity for fluoride was investigated by analyzing samples for different coating time. the coating amount was from 3% to 36%. with increasing coating amount. granule stability decreased and adsorption capacity increased. ftir analysis showed that the latex can react with active hydroxyl on the fe-al-ce adsorbent, which led to a decrease of the adsorption capacity. coated granules with a coating amount of 27.5% had a fluoride adsorption capacity of 2.22 mg/g (coated granules) at ph 7 and initial fluoride concentration of 0.001 m. a column test showed that 300 bed volumes can be treated with the effluent under 1.0 mg/l at an initial fluoride concentration of 5.5 mg/l, space velocity of 5 h(-1) and ph of 5.8. the coating granulation of the fe-al-ce adsorbent can produce granules that can be used in a packed bed for the removal of fluoride from drinking water.
