A two-site equilibrium model for absorption and ion exchange processes in molten salt the zeolite-A

The purpose of absorption and ion exchange processes using zeolite-A within the electrochemical actinide separation process is to reduce the high-level waste volume by selectively absorbing fission products from molten salt to the zeolite-A and recycling the cleaned salt. The purpose of the scaling factor nnz(i) is to prevent the above estimation algorithm from over-fitting relatively abundant Li, K and Na samples. The remaining 20 quaternary salt samples involving CsCl-NdCl3-LiCl-KCl and CsCl-SrCl2-LiCl-KCl were used to validate the model. The estimated V is 12.34 implying that occlusion site may accommodate 12.34 LiCl. S. Phongikaroon and M. F.
