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

open access: yesJournal 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 ...
