Description
The function of the accelerative effect exerted by succinic acid and calcium ion on the separation of uranium isotope by UO22+-Mal-Na+ ion exchange displacement system was studied. The chromatographic characteristics, separation factor ε and slope coefficient g as well as their temperature coefficients for the UO22+-Mal-Suc-Ca2+(NH4+) displacement system were studied and determined. By comparing the data obtained from the system described above with that from the UO22+-Mal-Na+ displacement system, it is found that the g increases by a factor of 63% or g x ε by 37% due to the accelerative effect exerted by succinic acid-Ca2+ on the mass-transfer of UO22+. It was also shown that the UO22+-Mal-Suc-Ca2+(NH4+) system is more adaptable for obtaining optimum experimental conditions because of its capability to control the pH of the solution involved in uranium-plateau
