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

Table 1

Initial and final pH during adsorption of Cr(VI) either on pure clay or micelle-clay complex. Initial concentration of Cr(VI) = 50 mg L⁻¹, contact time = 3 h, temperature = 25.0 ± 0.2°C, and adsorbent dosage = 5.0 g L⁻¹. Data represent averages of triplicates.
