Kinetic experiments demonstrated that up to 60% of the Cu adsorption occurred within the initial 4 h,and equilibrium was reached after 8 h,while up to 80% of the Cu desorption did within the initial 30 min,and equilibrium was reached after 2 h.

• 动力学实验表明,最初4h内的吸附量占总吸附量的60%25以上,8h后达到平衡; 而解吸在最初30min内占了近80%25,2h后可达平衡。
