Open publisher page 0 citations

Abstract

A method for the quantitative determination of rare earth admixtures in pure samarium and europium oxides was developed. The determination is possible within the limits 0.01 to 4%; 0.002 to 5%. The mean relative error is 3 to 5%. The minimum quantity of substance necessary for the analysis is 5 to 10 mg. (auth)
