Cadmium Removal from Contaminated Water Using Polyelectrolyte-Coated Industrial Waste Fly Ash

Figure 13

The influence of initial concentration on the removal efficiency of Cd (II) ions on FA based adsorbents (RFA, AFA, and PEFA) as a function of pH value of 9, 150 rpm mixing rate, contact time of 15 min, 4 g/L adsorbent dosage, 50 mL volume of aqueous solution, and 298 K temperature.
