The coefficients of distribution of 25 elements between KRF-20t-60 macroporous phosphonic acid cation exchanger and 0.1-2.0 M nitric acid have been determined by a static method. The above cation exchanger has a high affinity for some multivalent metal ions like Fe/sup (III)/, In/sup (III)/, Ce/sup (IV)/, Ti/sup (IV)/, etc. A mechanism has been proposed which explains the increase in cerium(IV) sorption with the rise of acid concentration above 2 M. An example of separation of an artificial mixture of lead and bismuth has been given.
