Equilibrium, Kinetic, and Thermodynamic Studies on the Adsorption of Cadmium from Aqueous Solution by Modified Biomass Ash

Figure 5

Plots of the pseudo-second-order kinetics for the adsorptions of Cd2+ on biomass ash and the synthesized matrix (initial concentrations of Cd2+, 100 mg/L; biomass ash concentration, 2 g/L; = 30°C; pH 5.0).
