Modern Methods of Separation and Determination of Radioactive Elements

Abstract A review is given of the new techniques of separation and determination of radioactive elements developed in recent years. Great progress has been achieved in obtaining and stabilizing actinides in unusual oxidation states, both high and low. On this basis a highly efficient extraction and sorption technique for the separation of elements is proposed. Application of bidentate phosphoro-organic reagents open up new prospects in the separation of elements in the trivalent state. Achievements in the development and application of luminescent and coulometric methods of actinide element determinations are considered. The techniques of determination of some radioactive elements in natural samples are discussed.
