The main objective of this work is to study the thermodynamic study and mathematical modeling of the adsorption of Co²⁺ ions on biopolymers based of  sugarcane bagasse (SCB) for to approximately the nature of the adsorption. The together of results obtained show that the adsorption process is favorable for a chemisorption and monolayer. Also, the adsorption process is expressed by the second order kinetic law. Thus the negative values of ΔG° and the positive values of ΔH° opt for an endothermic and spontaneous process. Also, the positive values of ΔS° indicate the increase in the randomness at the solid / liquid interface during the adsorption of the Co²⁺ metal ions.
