Removal of Cr(VI) from Aqueous Environments Using Micelle-Clay Adsorption

Figure 4

Effect of contact time on the removal of chromium by micelle-clay complex at pH 1 (♦) and pH 6 (■). Initial concentration of Cr(VI) = 50 mg L⁻¹, temperature = 25.0±0.2^∘C, and adsorbent dosage = 5.0 g L⁻¹. Data represent averages of total-Cr triplicate measurements (AAS) ± SE.
