Removal of Arsenite from Water by Ce-Al-Fe Trimetal Oxide Adsorbent: Kinetics, Isotherms, and Thermodynamics

Figure 3

As (III) adsorption capacity onto Ce-Al-Fe trimetal oxide adsorbent for different contact time and initial As (III) concentrations (pH = 7.0, initial As (III) concentration = 3, 8, and 10 mg·L⁻¹, the temperature = °C, and adsorbent dosage = 2 g·L⁻¹).
