Comparison of some of the analytical techniques and their applications to environmental radiostrontium determination
摘要
The knowledge about behavior of 90Sr in environment is of importance to prevent and control contamination. A large number of analytical methods have been developed for the determination of 90Sr in environmental samples. The conducted study was focused on interpretation and evaluation of the results obtained using three radiochemical procedures for the separation of 90Sr and/or 90Y including the classical procedures based on a series of semi-selective precipitations, the ion-exchange procedure and the use of fuming nitric acid. The acquired results showed a good agreement between the compared methods within the terms of accuracy and precision.
