Abstract: The uptake of cobalt from aqueous solution by Amberjet 1500H an ion exchange resin shows a remarkable increase in sorption capacity for cobalt, compared to both Amberjet 1300H and Amberlit IRC 86 ion exchange resins. All the studies were conducted by a batch method to determine equilibrium and kinetic studies. The experimental isotherm data were analysed using both Freundlich and Langmuir equations. The intraparticle diffusion rate constants in different temperatures were evaluated and discussed. Kinetic studies showed that the adsorption followed a pseudo-first or pseudo-second-order reaction. Thermodynamic studies reveal the feasible, spontaneous and endothermic nature of sorption processes. In addition to physical or chemical sorption processes according to nature of the resin used.
