摘要

A two-stage electrodialysis is investigated as an alternate method for the separation of plutonium and other heavy metals from aqueous chloride salt solutions. The first stage of the process separates heavy metals from solution through the formation of insoluble metal hydroxides within a three compartment electrodialysis cell. The second stage of the process utilizes a salt-splitting-electrodialysis to generate hydrochloric acid (3.8 M) and a mixture of sodium and potassium hydroxide (6 M). A material balance and proposed flow sheet for batch processes are included.
