Abstract
HOMOGENEOUS isotope exchange is usually investigated by methods in which after a certain time both chemical forms of a given element are separated, specific activities of fractions are measured, and the dependence on time of the exchanged mole fraction is examined. There are many suitable methods of separation, but all have considerable drawbacks—for example, incomplete separation, need for long time intervals for separation during which supplementary exchange can occur, and zero-time exchanges as a result of exchange induced by co-precipitation or separation1.
