PRIETO GARCIA, Julio Omar; RODRIGUEZ SUAREZ, Esnaider  e  MOLLINEDA TRUJILLO, Ángel. Research of kinetic and diffusive mechanisms in the adsorption of cu (ii) in sugar cane bagasse ash. cen. az. [online]. 2016, vol.43, n.4, pp. 36-41. ISSN 2223-4861.

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.
