When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).
