摘要
Inorganic ion exchange materials for the separation of 90Y from 90Sr include clinoptilolite, potassium titanosilicate pharmacosiderite, sodium titanosilicate and sodium nonatitanate. These materials are suitable for making a 90Y generator that contains 90Sr immobilized on an ion exchange column of the materials. The materials have a very high selectivity for 90Sr, a very low selectivity for 90Y, good radiation and thermal stability, low toxicity, fast reaction kinetics, and can be readily and reproducibly synthesized. A method is thus provided for eluting 90Y from the ion exchange material with an aqueous solution to obtain a carrier-free solution of 90Y.
