. The adsorption rate is found to accelerate with an increase in the amount of BF. Fig.1 Time dependence of Cd ion adsorption onto BF: (a) Time course; (b) Kinetics curves (Cd initial concentration: 0.1... constant (mmol?g-1?min-1). Plots of t/qt vs t for Cd-BF systems are shown in Fig.1(b). It can be seen that the adsorption process for Cd on BF follows the pseudo second-order kinetics. 3.3 Effect of pH......
