Abstract: In this study, bone char, cone char and cone active carbon due to being cheaper than commercial active carbon for removing fluoride from water was investigated. The effect of parameters such as pH, contact time and initial fluoride concentration were examined. Excel, SPSS software, ANOVA and t-test were used for data analysis. The direct experimental findings showed that efficiency rate of different adsorbents for concentration of 8 mg/L is noticeably different (p < 0.05), also for 6 mg/L concentration, the remarkable difference just reveals in active carbon and cone columns but it did not show any difference with bone char column (p < 0.05). The statistical result showed although the active carbon efficiency in 4, 6 and 8 mg/L has no different, it is significant for bone coal and cone (p < 0.05). It means the fluoride removal ability decrease for concentration more than 6 mg/L in bone coal and cone, but not in active carbon (p < 0.05). The results showed that these adsorbents are convenient and cheap absorbent for fluoride removal.
