A quantitative method was developed for the spectrophotometric determination of erbium and halmium in aqueous and alcoholic solutions in the presence of dysprosium and other rare earths which do not have absorption bands in the region of the spectrum taken for the analysis (erbium 522.2. m mu , holmium 536.5 m mu ). The determinations can be carried out within the limits of 0.05 to 1.0%. The accuracy of the method is 3 to 5%. An analysis of the fine structure of the complex absorption bands was made. It was shown that the parameters of the separate components of the complex band change differently when the aqueous medium for the absorbing ions is changed to an alcoholic one. (auth)
