Abstract
The elements La, Y, Pr, Nd, Sm and Ce form with Mg-II and purpurin (1, 2,4-trihydroxyanthraquinone) mixed-metal complexes which can be extrac ted into isobutyl methyl ketone at pH 7.5. The total content of these metals can be determined by measuring the magnesium absorbance by AAS. The proposed method, which permits the determination of concentration s at ppb levels, was applied to the analysis of synthetic samples with good results.
