“…The first step was characterised as the dissolution of HAP and the formation of a new stable Cd-apatite phase on its surface. In the second step, the stability of a new phase was further increased by the diffusion of Cd 2+ ions inside the HAP crystal lattice (Raicevic et al, 2005). The time necessary for achieving equilibrium depends on the amount of non-complexed metal ions in solution.…”

“…The large difference in phosphate contents (298.63mg/kg for POME & 53.02mg/kg for RS) perhaps is a factor contributing largely to the difference in immobilization efficiency of the two organic wastes. Phosphates addition to soil can enhance adsorption of metals ions or their precipitations as phosphates [8], [9].…”

“…Des travaux [11,12] ont démontré la faible solubilité dans l'eau et la grande stabilité des apatites de plomb, hydroxypyromorphite, Pb 10 (PO 4 ) 6 (OH) 2 , soulignant l'intérêt des apatites en terme de dépollution d'effluents aqueux mais également de sols contaminés [13,14] . Une étude de faisabilité de l'immobilisation du plomb par les cendres de combustion des farines animales dans des milieux aqueux a donc été réalisée.…”
