The book "Spectrophotometric and luminescent methods for determining lanthanides", written by a team of authors, including such specialists as Nikolai Sergeevich Poluektov, L. and . Kononenko, N. P. Ephryushina, S. In. Beltyukova and Anatoliy Terentyevich Pilipenko, represents an important contribution to the field of analytical chemistry and materials science . This is a publication published under the auspices of the Academy of Sciences of the Ukrainian SSR and the Physico-Chemical Institute named after A. In. It is aimed at researchers, students and practitioners interested in methods of analysis and definition of rare earth elements, in particular lanthanides. The book covers a wide range of topics related to the application of spectrophotometry and luminescence for the analysis of lanthanides - a group of elements that have unique physicochemical properties and are used in various industries, including electronics, optics and materials science. The authors consider in detail the methods that allow to accurately and effectively determine
