Abstract

The paper reports the sorptive responses of a newly developed adsorbent, activated alumina finely grinded with coconut shell powder. The efficiency of the sorption of fluoride ion is affected by pH, contact time, adsorbent dose, type and size of adsorbents. Contact time of mixed bed adsorbent (g/l) increase removal of residual of fluoride from 0.7 to 1.8 mg/l. Optimum pH range 6, (alkalinity range 4 mg/l) is found to reduce fluoride level to 0.8 mg/l.
