Overexposure to fluorides causes dental, skeletal, and crippling fluorosis. Population growth droughts in Kenya recently necessitated the sinking of boreholes supply drinking water. The water fetched from contains a high concentration fluorides, consequently increasing prevalence dental Bone char remains sustainable adsorbent remove as it is environmentally friendly, has efficiency, easy use, low cost compared other adsorbents or fluoride removal methods that may be technically non-feasible rural communities. This study using bovine goat bone chars. Bovine chars were prepared by calcining muffle furnace at 400°C 600°C. made appeared gray while those 600°C darker. was activated 1 M H<sub>2</sub>SO<sub>4</sub> ratio 40 ml per 2 g contact time 24 hours. also grey. surface functional groups examined infrared spectroscopy (FT-IR), which revealed similar both their parts, with notable differences peak depths. amount inorganic materials determined portable X-ray fluorescence (XRF) showed concentrations Ca, P, Mg, Si, Al, Fe, S, K, Mn Ti decreasing before after H<sub>2</sub>SO<sub>4</sub>. adsorbed ppm below WHO-recommended limits 30 minutes, removing 66.8% 61.8% initial concentrations.
