SELECTED PHYSICAL PROPERTIES OF BONE CHAR AND SODIUM TITANATE... 

Bone Char. Bone charcoal is a carbonaceous substance derived from the carbonization of selected grades of animal bones by heating dry bones in an airtight iron retort at 500-700°C for about four to six hours. Comparing the capacity of metal ions removal with aetivated carbon, bone charcoal provides not only a porous carbon surface for physical adsorption, but also a hydroxyapatite lattice—Ca,o(P04)g(OH)2 for ion exchange of metal ions. Based on these properties, this sorbent should have excellent adsorption capacities for metal ions. The charaeteristies of typieal bone char are shown in Table 15.9.
