The ash obtained from Tridax procumbens leaves was used to adsorb cadmium from aqueous solution of Cadmium chloride. The sorption process with respect to its metal ion concentration, pH, contact time and particle size on adsorption were studied. The percentage removals with respect to the parameters were also studied. The most effective pH range was found to be 5.8-6.0 for sorption of metal ions. The first order rate equation by Lagergren was tested on the kinetic data and the adsorption process followed first order rate kinetics. Isotherms data were analyzed for possible agreement with Langmuir and Freundlich adsorption isotherms; the model for dynamics of metal ions uptake proposed in this work fitted the experimental data reasonably well for Freundlich adsorption isotherm than Langmuir adsorption isotherm. The correlation coefficients (R2) were 0.998 and 0.912 for Freundlich and Langmuir isotherms respectively.
