Fig. 2. The effects of pH on the removal of Sb(iii) and Cd(ii) from a binary system using (a) BC and (b) MnFe2O4–BC at room temperature for 24 h; the removal of Sb(iii) and Cd(ii) from a binary system at pH 7.0 using (c) BC and (d) MnFe2O4–BC at room temperature, after different contact times; and the effects of initial concentration on the removal of Sb(iii) and Cd(ii) from a binary system at pH 7.0 using (e) BC and (f) MnFe2O4–BC.
