CuO nanopowder for removal of Pb(II) and Zn(II) [PDF]

Journal of Environmental Engineering and Science, 2015
Metal oxide nanopowder, namely copper oxide nanopowder, was prepared. The produced metal oxide was characterised and used as a potential adsorbent for removal of lead(II) and zinc(II) from an aqueous solution. The rate of uptake of lead(II) and zinc(II) was found to be rapid in the first 10 min, and after 150 min, the amount of lead(II) and zinc(II ...

The adsorption of Cd(II) and Pb(II) to chitin in seawater [PDF]

Journal of Colloid and Interface Science, 1990
The adsorption of Cd2+ and Pb2+ to the surface of chitin has been studied in seawater as a function of pH (2 to 8), temperature (5 to 60°C), salinity (4 to 36), and the presence of other transition metals. The rates of adsorption were quite rapid () and were affected by the presence of other metals such as Cu2+.
