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

Figure 2

As (III) adsorption capacity onto Ce-Al-Fe trimetal oxide adsorbents with different Al/Fe/Ce molar ratio (pH = 7.0, initial concentration of As (III) = 20 mg·L⁻¹, the temperature = °C, and adsorbent dosage = 2 g·L⁻¹).
