《Adsorption of Cu and Ni Ions from Aqueous Solutions by Commercial Activated Carbon and the Reutilization in Glass Coloration》
where qe and qt are the amount of analyte（mg/g）at equilibrium and at any time，respectively.K1 and K2 are the equilibrium rate constants of pseudo-first-order and pseudo-second-order adsorption（min-1），respectively.A comparison of the R2 values（Table 2）shows that the pseudo-second-order kinetic model fits better with the higher values data（R2=0.999 6 and 0.999 5）for both Cu（II）and Ni（II）.The results suggest that the adsorption of Cu（II）and Ni（II）ions on the AC adsorbent is controlled by the chemical process through the sharing of electrons or covalent forces through exchanging of electrons between adsorbent and adsorbate[21].
