In the present work, the removal of lead and cadmium, metals highly hazardous to humans and the environment, from a standard solution using bovine bone as a natural adsorbent is presented. Bone is mainly constituted by calcium apatite known as hydroxyapatite (HAP), which is a transparent-translucent solid and poorly soluble in water. The ionic character of PAH [Ca10(PO4)6(OH)2], gives it the capacity for partial or complete substitution of network ions by others of similar size. The main objective is to develop a simple and effective technique to help prevent and remediate the contamination of aquifers with heavy metals such as lead and cadmium.…mehr
