A basic investigation on the kinetics of adsorption of Copper (II) ion from aqueous solution by activated carbon prepared from bark of Erythrina Indica has been carried out under batch mode. The influence of various parameters such as effect of initial concentration, adsorption dose and agitation time were studied. Experimental data were fitted into linearised form of Lagergren and Ho kinetic equations for pseudo first order and pseudo second order models respectively. The kinetic parameters have been calculated and discussed in detail. The results revealed that the adsorption of Copper (II) ion onto chosen adsorbent followed the pseudo first order kinetics. Intra particle diffusion was confirmed as one of the rate determining steps using Webber Morris plot parameters.
