Temperature-responsive alkaline aqueous biphasic system for radioactive wastewater treatment
文献摘要：
The treatment of anionic 99TcO4-in the waste tank with high alkalinity is still very challenging.In this work,a new temperature-responsive alkaline aqueous biphasic system(ABS)based on(tri-n-butyl)-n-tetradecyl phosphonium chloride(P44414Cl)was developed to remove radioactive 99TcO4-.The phase tran-sition mechanism was studied by cloud point titration,small-angel X-ray scattering,dynamic light scatter-ing,and molecular dynamic simulations.As the NaOH concentration or temperature increased,the P44414+micelle could grow and aggregate.This micelle showed a particularly high affinity toward ReO4-/99TcO4 compared to other competing anions and could directly extract more than 98.6％of 99TcO4-from sim-ulated radioactive tank waste supernatant.Furthermore,the loaded 99TcO4-could be easily stripped by using concentrated nitric acid rather than metal salt-based reductants.This work clearly demonstrates that the alkaline ABS is a promising separation system for solving the technetium problem in the alka-line waste tank.
