| Abstract: | In this paper a simple, sensitive method for the determination of eu-ropium in samarium and gadolinium oxides using a graphite tube lined withtantalum foil is described. The effects of hydrochloric acid concentrationand samarium and gadolinium matrix are discussed.The method can be useddirectly for the sample analysis without predissociation of matrix. |
