Removal of Cr(VI) and Cu(II) Ions from Aqueous Solution by Carbon Prepared from Henna Leaves
Figure 1
(a) Effect of contact time on the removal of copper by adsorption of the henna leaves at initial concentrations of 50 ppm, 70 ppm, 90 ppm, and 100 ppm, pH 7, and 1 g adsorbent dose. (b) Effect of contact time on the removal of chromium by adsorption of the henna leaves at initial concentrations of 50 ppm, 70 ppm, 90 ppm, and 100 ppm, pH 7, and 1 g adsorbent dose.
