Outline
The synthesis of a polyethylene imine-functionalized biochar aerogels (LSBC-CTS/PEI) using lotus seed powder, chitosan and polyethylene imine as materials, and used for adsorption of U(Ⅵ) in wastewater was studied. The results show that LSBC-CTS/PEI exhibit a looser structure with interconnections, and contains very rich amine-based functional groups, which can provide more adsorption sites for U(Ⅵ) coordination. The selective adsorption of U(Ⅵ) by LSBC-CTS/PEI is greatly affected by pH. The adsorption is mainly composed of single-layer chemisorption, which belongs to a spontaneous endothermic process, and is more suitable for description by quasi-second-order kinetics and Langmuir isothermal adsorption model. The selectivity of LSBC-CTS/PEI to uranium is 84.91%, and the maximum adsorption capacity is 533.89 mg/g. The adsorption material has high adsorption capacity of uranium, good selectivity, and convenient separation of solid and liquid, so it has the certain value of application.
