Adsorptive Accumulation of Cd(II), Co(II), Cu(II), Pb(II) and Ni(II) Ions from Water onto Kaolinite: Influence of Acid Activation

Naturally occurring kaolinite and its acid-activated form were used to separate the toxic metal ions Cd(II), Co(II), Cu(II), Pb(II) and Ni(II) from water by adsorption. Kaolinite was treated with 0.25 M H 2 SO 4 to obtain the acid-activated form. Adsorption onto the calcined forms of the clays was i...
