The isotope effects of gallium (69/71Ga) and indium (113/115In) have been
determined in the system: strong cation exchanger (Dowex 50-X8)/HCl. The sings of gallium and indium
effects were opposite, i.e., the heavier isotope of gallium was fractionated into the resin phase,
while the heavy isotope of indium was fractionated into the liquid phase. The values of unit
separation gains were found to be +3.0 ´ 10-5 for gallium
and –2.0 ´ 10-4 for indium. A possible explanation of the
effects is proposed.
