Abstract
The objective of the current study is the application of oceanic polymetallic nodules and cobalt-rich curst leaching residues. The phase composition, specific surface area and pore structure are measured. The experimental results show that the leaching residues with huge nano mineral particles have significant potential in environmental protection because of their large specific surface area and surface activity. The nano properties can be used for the disposal of heavy metal effluent with Cu2+, Pb2+ and Cd2+. And the influence of adsorption time, pH value and initial solution concentration on the adsorption effect are investigated. The maximum volume and adsorptive capacity of oceanic polymetallic nodules and cobalt-rich curst leaching residues to treat heavy metal waste water can be determined via the adsorption experiments.
