Deskripsi
In this paper the extraction and separation of cerium/fluorine in fluoride-bearing cerium sulfate solution with fluoride coordination agent has been studied. The UV-vis spectra suggest that Zr<sup>6+</sup> and Al<sup>3+</sup> can scrub the F<sup>-</sup> from [CeF<sub>2</sub>] <sup>2+</sup> complex. The separation and conductivity studies show that aluminum salt is the most suitable fluoride coordination agent, and an ion-exchange reaction is involved between Ce<sup>4+</sup>/ [CeF<sub>2</sub>] <sup>2+</sup> and hydrogen ion.
