According to Fig nbsp a the adsorption amounts of HM

According to Fig. 7a, the adsorption amounts of HM-IMs-5 and HM-NIMs-5 increased fast within the initial 50 min, and achieved 92.06% and 88.08% of the equilibrium capacity at 120 min, finally reached equilibrium within 6 h. HM-IMs-5 presented a much higher adsorption equilibrium capacity than HM-NIMs-5, owing to the specificity of imprinted cavity for BF. From Table 2, the kinetic data was fitted by pseudo-second-order kinetic model (R2 > 0.99) better than by pseudo-first-order kinetic model, which suggested that NHS-LC-Biotin the chemical process could be the rate-limiting step during the adsorption for BF [39]. And the calculated Qe values (Qe,c) of pseudo-second-order kinetic equation were also close to the experimental data (Qe,e). The values of h and t1/2 in Table 2 also indicated glial cells the sorbents had excellent kinetic properties.
