On the method of anion exchange separation of americium, plutonium, neptunium and uranium

Technique of anion exchange separation of americium, plutonium, neptunium and uranium using VP-1AP anionite with their consequent determination by means of α-spectrometry is presented. Variation coefficients calculated on the ground of 20 experiments conducted using model solutions constitute 5,7 and 7%, respectively, for Am, Pu and Np. Technique provides for reliable results at analysis of solutions which do not contain essential amounts of inert materials and with content of 241Am, 238Pu and 237Np from 4-5 Bq, while of 234U studing from 9 Bqu
