The objective of this investigation was to evaluate the adsorption capacity of Cd +2 through chemical activation of the adsorbent obtained from chicken feathers, for which a methodology for obtaining the adsorbent and determining the optimal carbonization temperature it was obtained three adsorbents with different treatment: unactivated (CSA), activated acetic acid at 15 v/v % (CAA) and activated with potassium hydroxide at 25 m/v % (CAB). The physicochemical characterization of the adsorbents obtained was carried out having a range of values of surface area (18.74 - 73.48 m 2 /g), ash percentage (13.16 - 22.34 %), apparent density (0.34 - 0.68 g/ml), humidity percentage (0.86 - 1.06 %) and pore volume (0.03 - 0.09 ml/g); An FTIR analysis of the 0.075 mm adsorbents (Mesh No. 200) was also carried out in which a similarity was observed, showing functional groups belonging to Amines and Amides. The effect of adsorbent treatment, pH and particle size was evaluated between the adsorbents obtained, with the unactivated adsorbent and the one activated with potassium hydroxide (both at pH 6 and particle size of 0.075 mm) having values of 7.50 mg/g and 7.38 mg/g adsorption capacity respectively. The maximum adsorption capacity at equilibrium was determined using adsorption isotherms of the adsorbent obtained, resulting in qmax=7.80 mg +2 Cd /g adsorbent and that the adsorption process is best described with the isotherm of the Freundlich model.
