Aluminum oxalate as adsorbent was used by authors for preparing traditional soil pots to minimize fluoride content in drinking water samples. The adsorbent dose was varied in the range of 2 g to 8 g per 500 g soil. Langmuir and Freundlich isotherms curves were also plotted. pH, TDS, hardness, fluoride and aluminum parameters were also examined in residual water samples. Maximum fluoride removal efficiency of adsorbent was studied.
