Effect of different concentrations of (a) MB dye and (b) Cr (VI) ions on adsorption capacity qe (mg g−1) for each ABHG concentration and Effect of contact time on adsorption of (c) MB dye and (d) Cr (VI) ions on ABHG (Time for MB dye = 90 min, pH for MB dye = 7.2, pH for Cr (VI) ions = 1.04, Time for Cr (VI) ions = 180 min, Temp. = 25 °C).
