The objective of this investigation was to evaluate the adsorption capacity of diesel B5 S-50 by using the bioadsorbent obtained from chicken feathers. For this, a methodology was developed to obtain the bioadsorbent, which consisted of collecting chicken feathers, which were later washed, dried, crushed, sieved, and activated with acetic acid and 3.5% hydrogen peroxide. (v/v), obtaining three samples of bioadsorbents. The physicochemical characteristics for the three bioadsorbents were determined: without activation, activated with acetic acid and activated with hydrogen peroxide, obtaining real density values of 0.975 g/ml, 0.977 g/ml and 0.978 g/ml respectively, for the apparent density. the results were 0.018 g/ml, 0.015g/ml and 0.018 g/ml respectively, for the percentage of porosity 98.100%, 98.500%, 98.200% respectively were obtained, in the percentage of humidity values of 10.100%, 8.653 were reported. %, 9.210%, for the percentage of ash values of 3.300%, 1.6%, 1.800% were obtained, regarding the surface area the values of 23.52 m 2 /g, 49.41 2 m /g and 43.02 m2/g were obtained, respectively. Likewise, an FTIR analysis was carried out in which the presence of Amide A and B was observed, and Amides I, II and III in the three bioadsorbents. Likewise, an analysis of the morphology of the bioadsorbents was carried out using the SEM method, which helped to observe the bioadsorbents with a better resolution and approaches. Finally the dynamic degradation test was carried out using the ASTM F726- 12 in which the oleophilic properties, buoyancy and the amount of water retained by each bioadsorbent were determined. The results of this test were that the three bioadsorbents presented buoyancy and the amount of water retained was 0.418 g of water/g of bioadsorbent. without activation, 0.629 of water/g of bioadsorbent activated with acetic acid and 0.746 g of water/g of bioadsorbent activated with hydrogen peroxide. The diesel adsorption capacity was determined by applying the ASTM F726-12 Standard, in which a short test (15 minutes) and a long test (24 hours) were considered, being the bioadsorbent activated with acetic acid the one that presented the best results, with an adsorption capacity of 10.796 g of diesel/g of bioadsorbent for a contact time of 24 hours and with a particle size of 6.3 mm. The effect of the particle size and the activation of the bioadsorbent was evaluated, where the particle size has a significant effect on the adsorption capacity of diesel B5 S-50, of all the results obtained, the particle size of 6.300 mm obtained the values highest adsorption capacity compared to the particle size of 2.000 mm, regarding the activation of the bioadsorbent, the one that stood out with the best results in all the experimental tests was the bioadsorbent activated with acetic acid, also through a statistical analysis it was verified that the Activation of the bioadsorbent has an effect on the adsorption capacity, the effect of contact time was also evaluated, which had a significant effect on the adsorption capacity, highlighting the contact time of 24 hours compared to 15 minutes. Finally, to evaluate the kinetics of adsorption, times between 0.5 min and 20 min were taken into account, in which it was possible to observe that in a time of 15 min the diesel adsorption equilibrium was reached with a value of 10,452 g of diesel. /g of bioadsorbent, an evaluation was also carried out for times between 5 min and 80 min, and the diesel adsorption equilibrium was reinforced at... min with a value of... Likewise, the kinetic model of pseudo- second order was the one that best describes the adsorption kinetics, with R2 conversion coefficients equal to 0.99. It is concluded that the evaluation of the biosorbent obtained from chicken feathers complies with the parameters established by the ASTM F726-12 Standard to be applied as a Type III hydrocarbon biosorbent.
