Abstract: The removal of Fluoride from synthetic sample by adsorption on chemical activated carbon (CaCl2) prepared from Phoenix Dactylifera (Date Plam) seeds have been carried out at room temperature 32 ± 1 oC. Batch tests were conducted for the removal of Fluoride on chemically activated carbon with Impregnation ratio’s (I.R) 0.25, 0.50 and 0.75 for optimum time, optimum dosage and optimum pH. The maximum removal efficiency was obtained at an I.R. ratio of 0.75. The optimum contact time, adsorbent dose and pH for carbon with I.R-0.75 was 40min, 140mg and 7.00 respectively, with fluoride removal efficiency of 93%, 93.5% and 94.5% respectively has been observed
