Fabrication and characterization of adsorbents from corn husk and pomegranate peel for platinum recovery from model media and intact extraction supernatant of Pt-Sn/Alumina and Pt-Re/Alumina industrial spent catalyst was investigated. Two adsorbent samples are prepared using corn husk and pomegranate peel via acid and diethylamine treatment. The adsorbents are characterized and the adsorption of platinum onto the adsorbents is examined using model media and real solutions. These characterization analysises indicate that the amine immobalized corn husk and amine immobalized pomegranate peel adsorbents have the amorphous structure. Also the amine immobalized corn husk and amine immobalized pomegranate peel adsorbents are more pure than the acid treated corn husk and acid treated pomegranate peel adsorbents respectively, and contain more nitrogen and hydrogen elements than acid treated corn husk and acid treated pomegranate peel adsorbents. This results in purer final product and also because of more nitrogen and hydrogen elements the amine immobalized corn husk and amine immobalized pomegranate peel adsorbents, have more affinity to adsorbed platinum ions from the solutions. The presense of active hydroxyle and C=O functional groups on the surface of adsorbents improves their adsorption affinity to platinum ions. The average particle size of amine immobalized corn husk adsorbent and amine immobalized pomegranate peel adsorbent are 502 and 1300 nm. Adsorption results indicate that hydroxyl and amine functional groups are responsible for adsorption of platinum onto the adsorbents, and immobilization of amine functional groups enhances the adsorption. Adsorbents show appreciable affinities for relative selective adsorption of Pt. Aluminates interfere in adsorption of platinum ions. The adsorption capacity of the corn husk adsorbent with immobilized amine functional group for model media and intact supernatant (from pt/Sn alumina catalysis) is 38.5 mg Pt/(g adsorbent) and 7.8 mg Pt/(g adsorbent), respectively. Also the adsorption capacity of the pomegranate peel adsorbent with immobilized amine functional group for model media and intact supernatant (from pt/Sn alumina catalysis)is 5.64 mg Pt/(g adsorbent) and 3.78 mg Pt/(g adsorbent), respectively. The interference of aluminates is believed to be responsible for the reduced adsorption capacity. Platinum is obtained in elemental form when adsorbent is burnt (calcined) after the saturation. Platinum product purity for adsorption from Pt/Sn solution is about 53.8 and 52.8 percentage for amine immobalized corn husk and amine immobalized pomegranate peel adsorbents respectively. And Platinum product purity for adsorption from Pt/Re solution is about 80.1 and 86.5 percentage for amine immobalized corn husk and amine immobalized pomegranate peel adsorbents respectively. These result show that amine immobalized corn husk adsorbtion capacity is higher than amine immobalized pomegranate peel adsorbents adsorption capacity but amine immobalized pomegranate peel adsorbents selectivity for Pt ions is higher than amine immobalized corn husk adsorbent selectivity. Further, structural changes induced by chemical treatment of the corn husk is explained by Mannich type mechanisms. Dead-end adsorption data indicates that the kinetics of adsorption of Pt onto the sorbent follows a pseudo-second order adsorption model. The pseudo-second order rate constant (k 2 ) for Pt ion adsorption for amine immobalized corn husk and amine immobalized pomegranate peel adsorbent are 0.00436 and 0.004091 g/mg.min respectively. The pseudo-second order rate constant (k 2 ) for Sn ion adsorption for amine immobalized corn husk and amine immobalized pomegranate peel adsorbents are 5.13891 and 22.91514 g/mg.min respectively. Whole results show a good affinity of synthetized adsorbents for Platinum ion and also the Re removal stage results in aluminum removal from solution and the purer Pt final produst.
