“…However, impurities such as Fe, Al, Ca, La, Zr, Mg, and other metals can be dissolved in the electrolyte solution as an ion form if the elements were not clearly removed in the step of chemical separation. Several publications have reported Al 3+ , Fe 3+ , F − , K + , Mg + , Zn 2+ , Ca 2+ , Ba 2+ , Lu 3+ , and Eu 3+ decrease the deposition yield, and increase the FWHM value [114][115][116], while Na + does not greatly affect them [101]. Donnan and Dukes developed a carrier method using a 10 μg of 238 U carrier to increase the electrodeposition yield of 244 Cm, 241 Am, 233 U and 237 Np [117].…”
