KINETICS OF ION EXCHANGE IN POLYDISPERSE SYSTEMS Ⅲ. APPLICATION OF RATE EXPRESSIONS FOR HETEROGENOUS ISOTOPIC EXCHANGE

For comparison with results obtained with uniform systems, further numerical calculations are performed for several important frequency distributions of the particle radii. From these numerical calculations, it can be concluded that the ratio of standard deviation and mean radius must not be more than 0.1 so as to avoid an error resulting from calculations with this expression for uniform systems.
