The proposed method for determining content of dysprosium in product consists in treating the product sample with standard solution of sodium chloride and organic reagent in the presence of buffer solution, exposing the sample to ultraviolet radiation, and measuring the intensity of the luminescence of the solution within a time interval of 0.05 ... 10 ?s. As the organic reagent, 3-(6-benzodioxanil)-pyrazole-5-carbonic acid is used. As the buffer solution, sodium acetate solution with pH = 3.45 ... 3.55 is used.
