摘要: The adsorption of ammonia gas on nanoparticle hydroxyapatite (HA) prepared from bovine bone was investigated. HA is well known as a good adsorbent for both and liquid adsorbate. In this study, cleaned, calcined at 700 °C 4 hrs subsequently ground. ground powder the starting material synthesize via precipitation. As-precipitated nanoparticles were filtered, washed finally 500, 700, 1000 °C. Phase analyses performed by X-ray diffraction (XRD) result showed that higher temperature, degree crystallinity. (NH3) indicated as-precipitated with low crystallinity displayed better activity to NH3 than high
