The possibilities of the sorption-spectroscopic determination of the sum of rare-earth elements have been studied on an example of La, Gd, and Yb as representatives of the light, middle, and heavy rare earth elements. The determination is carried out after the sorption from solutions with pH 3 onto the surface polyacrylonitrile fiber loaded with a Chel-100 ion exchanger followed by complexation with Chlorophosphonazo III. A dynamic version of the sorption-spectroscopic determination of the sum of La, Gd, and Yb has been developed for the concentration range 5–30 ng/mL with a detection limit of 3 ng/mL. The method was tested in the analysis of model solutions of CaCl2, FeCl3, and TiCl4; RSD < 20%.
