Extracting Metals by Electrolysis

The reactivity series and metal extraction The reactivity of a metal determines how it is extracted. Metals above carbon in the reactivity series must be extracted using electrolysis. Metals less reactive than carbon can be extracted from their ores by reduction. Copper, silver, gold and platinum can occur in their pure form (natively) and do not

Abstract The sorption behaviour of carbon nanotubes (CNTs) toward some divalent metal ions such as Cu(II), Co(II), Ni(II), Zn(II), Pb(II), Mn(II) and Cd(II) has been investigated systematically. The affinity order of the metal ions towards CNTs at pH in the range of 7.0–9.0 was: Cu(II) > Pb(II) > Zn(II) > Co(II) > Ni(II) > Cd(II) > Mn(II). The experimental parameters for preconcentration of ...
