Biosorption potential of Pennisetum glaucum has elaborated by investigating its kinetic behavior in nonlinear fashion. RMSE values supported the pseudo second order (PSO) and elovich model, but correlation coefficient (R2) values supported the PSO only. Study of intra-particle diffusion model (IPDM) and Boyd plots revealed the multi-linear diffusion pattern of the studied metal ions toward biosorbent. Initially, IPDM was found to be the rate-determining step, however boundary layer diffusion was found to be the slowest step later on.
