Abstract

The sorption kinetics and intra-particulate diffusivity of cadmium (11) and lead (11) ions onto okra derived cellulose biomass were studied. The results showed the sorption kinetics involved a saturation profile depicting time dependent saturation. More than ninety-seven percent of the cadmium and lead ions were sorbed from the aqueous environment. The fractional attainment of equilibrium for each of the metal ions studied showed rapid sorption process. The evaluation of the kinetic parameters that affect sorption processes depicted that the process for both cadmium and lead ions sorbed using okra derived cellulose biomass as sorbent material is particulate diffusion controlled.
