Determination of the Efficiency of Praseodymium Ion Sorption at Various Ratio by the Amberlite Ir120 (H+ ):Ab-17-8 (Oh- ) Interpolymer System

Introduction. The aim of this study was to investigate the efficiency of praseodymium ion sorption using ion exchange resins containing Amberlite IR120 (H+) and AB-17-8 (OH-) at different composition ratios.Goals and objectives. The study established how conformational changes based on “long-range action” affect the efficiency of praseodymium ion sorption; the features of sorption of this ion in a static mode were studied.Methods: The study clarified the effect of resin composition on the sorption efficiency through a comprehensive experimental analysis, including sophisticated sorption experiments and characterization methods such as spectrophotometry and atomic emission spectroscopy. Results and analysis. Optimal coefficients providing the maximum efficiency of praseodymium ion removal were determined. In addition, the study examines the underlying mechanisms that determine the sorption properties, focusing on the relationship between resin composition, surface chemistry, and ionic interactions. Conclusion: The results obtained will not only contribute to the development of specialized ion exchange materials for the efficient recovery and purification of praseodymium, but also to a deeper understanding of ion exchange chromatography processes. This study is of great importance for praseodymium-dependent industries, as it offers strategies to address challenges associated with its production, purification, and use.
