SEPARATION OF IRON FROM RARE EARTHS

The possibility of a simple separation of iron from rare earths on the strongly basic ion exchanger OAL was investigated. In hydrogen chloride medium, the rare earths are generally not bound as iron is. The iron can be eluted with water and determined in the usual manner. The method can be used for the separation of iron from rare earths as well as for the determination of iron in rare earths. (tr-auth)
