Abstract

Abstract The removal of arsenic in geothermal water was carried out by using hydroxyapatite-based materials including the industrial waste, such as bovine bone and hydroxyapatite modified by a solid solution with SiO2 (SiAp). The existence of arsenic in hydroxyapatite was examined by XANES measurements. The use of these hydroxyapatite-based materials results in a significantly lower environmental loading approach in order to purify arsenic contamination of drinking well waters.
