  • Recycling of shell wastes into nanosized calcium

    The carbonate ions in the shell and NaClO-treated CaCO 3 powders were demonstrated by the internal vibration modes, i.e., 700 cm −1 (ν 4b), 713 cm −1 (ν 4a), 858 cm −1 (ν 2), 1082 cm −1 (ν 1), 1484 cm −1 (ν 3b) and 1525 cm −1 (ν 3a). These active modes corresponded to the absorption of aragonite phase.

    Then carbonate ions combine with Pb 2+ in solution to form lead carbonate precipitates. So the process is that a high solubility product of calcium carbonate (Ksp = 8.7 × 10 −9) is converted to a low solubility product of lead carbonate (Ksp = 3.3 × 10 −14). In this process, the mechanical activation accelerates the reaction by reducing ...
