Adsorption kinetic curves of TC onto RBC, KMBC, 1% HAs/KMBC and 10% HAs/KMBC: (a) the solid lines and dotted lines are the pseudo-second-order model and the pseudo-first-order model simulation, respectively; (b) Intra-particle diffusion model simulation. C_0(TC) = 50 mg/L, m/V = 0.1 g/L, T = 25 °C, pH = 7.0.
