ESTUDIO DE LOS MECANISMOS CINÉTICOS Y DIFUSIVOS EN LA ADSORCIÓN DE Cu (II) EN CENIZA DE BAGAZO DE CAÑA DE AZÚCAR.

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. [ABSTRACT FROM AUTHOR]
