摘要：

Hydroxyapatite (HAP) were synthesized from Pensi (Corbicula moltkiana) sheels by hydrothermal method and used as adsorbent for peat water purification. Batch adsorption experiments were performed to investigate the effects of various factors such as contact time, adsorbent dosage, and pH. The obtained materials were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and scanning electron microscope (SEM). Results showed that HAP calcined at 900 degrees C (HAP900) and 1000 degrees C (HAP1000) have a poorly crystalline shape. HAP900 also contain Tetracalsium Phosphate (TTCP) with a Ca/P molar ratio 2.18, while HAP 1000 contain HAp with a Ca/P molar ratio 1.67. Optimum condition for peat water purification with HAP900 and HAP1000 were both achieved at 1 hours, 1 grams adsorben mass at pH 2. SEM micrographs show that after purification, the surface of HAP were covered by organic compounds from peat water.
