Abstract: A higher derivative spectrophotometric method for the determination of individual rare earths has been developed. The method described appears quite adequate in terms of rapidity and simplicity and has been applied to the determination of Pr, Nd, Sm, Eu, Dy, Ho, Er and Tm in mixed rare earth samples with satisfactory results.
