In this study bean pod red cargamanto (BPRC) was evaluated as biosorbent for removal of cadmium (Cd 2+ ) in aqueous solutions, with the characterization of the material, it was determined that the BPRC is mainly acidic and has functional groups on its surface which provide the ability to adsorb metal ions such as cadmium (Cd 2+ ).The effect of pH and Cd 2+ concentration on biosorption was analyzed.It was found that the optimal conditions for the process are pH 8 and 100 mg L -1 of Cd 2+ .From the optimal conditions found, it was determined that the material has an adsorption capacity of 0.070 meq g -1 (3.907 mg g -1 ) of Cadmium (Cd 2+ ), with a removal percentage of 78.1%.In the biosorption equilibrium, the best fit was a Freundlich isotherm with an intensity (n) of 2.547 and a correlation coefficient R 2 of 0.980.Kinetic behavior analysis showed the process reaches steady state within 30 minutes of contact.The fit of the experimental data indicates that the pseudo second order model is one of the most accurately describes the results.The kinetic coefficient (K 2 ) obtained for the model presented a value 1.135 g meq -1 min -1 for a correlation coefficient value of 0.999.
