FIELD: analytical methods. SUBSTANCE: samarium is converted into complex compound with organic reagent, in particular sulfosalicyl-S-(4-bromoanylide) methyl ester, in presence of cationic surfactant, namely decylpyridinium chloride. Samarium/organic solvent/surfactant ratio is 1:15:13, pH = 6.7 +/- 0.05. Simultaneously, Tb, Dy, Sm, and Eu can be determined. EFFECT: increased selectivity and reproducibility. 2 cl
