Simultaneous extraction and preconcentration of some metal ions using eucalyptus-wood based activated carbon modified with silver hydroxide nanoparticles and a chelating agent: optimization by an experimental design

In the present work, the solid phase extraction (SPE) of Cr( iii ), Cu( ii ), Pb( ii ), Ni( ii ), Cd( ii ), and Co( ii ) metal ions was carried out using a new adsorbent, activated carbon modified with silver hydroxide nanoparticles and a chelating agent.
