A Comparative Study of the Adsorption of Transition Metals on Kaolinite

Adsorption of Pb(II), Cu(II), Zn(II), Co(II), and Mn(II) to kaolinite was measured at 25°C in the presence of 5 mM KNO3. Adsorption edges (pH 3–10; total metal concentration 100 μM) for Pb(II) and Cu(II) were sigmoid, but those for Zn(II) and Co(II), and especially Mn(II), were characterized by dist...
