ABSTRACT | Heavy metal ion contamination in drinking water poses a major risk to human health, whilst contamination in wastewater streams can cause damage to the wider environment. In this study carbon nanocages, synthesised using a supercritical fluid deposition method, were examined as adsorbents of Pb2+ ions from aqueous solutions. Through careful selection of the catalyst and the carbon deposition temperature and pressure, high yields of nanocages with surface areas up to 1175 m2 g−1 were synthesised. These high surface area materials were subsequently tested for their ability to absorb Pb2+ ions, as a function of pH, from simulated wastewater. The nanocages were found to be effective at removing the Pb2+ ions at levels of 11.1 mg g−1, compared to 7.6 mg g−1 for commercially available activated carbon. The kinetics ofmetal ion adsorption by the nanocages and activated carbon can be described by a pseudo-second-order kinetics model, with a rate coefficient (k2) of 4.8×102 g mg−1 min−1. | ||
