Abstract

In this paper a kinetic and diffusive study regarding adsorption of ions Cu (II) on a sample of sugar cane bagasse ash is made. The results show that the second-order
kinetic model better adjusts the experimental data than the Elovich and first-order kinetic model. The diffusive mechanism study shows that the diffusion in the liquid pellicle and in the micro-pores of the adsorbent prevail in the adsorption phenomenon.
