This study reports the optimization of pyrolysis process for the synthesis of bone char for fluoride removal from water. Specifically, we have performed a detailed analysis of the adsorption properties of bone char samples obtained at different operating conditions of pyrolysis. Results show that the pyrolysis temperature plays a major role to synthetize an effective bone char for water defluoridation. In particular, a pyrolysis temperature higher than 700 °C may cause the dehydroxylation of the hydroxyapatite of bone char affecting its fluoride adsorption capacities. The best adsorption properties of bone char for fluoride removal are obtained with those samples synthetized …
