Description

This work is devoted to the study of sorption materials for use in the sample processing device of the MIKS monitoring system of xenon isotopes. The aim of the work was to select new materials with improved sorption characteristics with respect to xenon to ensure stable xenon extraction and reduce the minimum detectable concentration (MDC) for the Xe-133 isotope. To determine the sorption properties of materials with respect to xenon, the preparative gas chromatography method was used. The following zeolites were selected as materials: CaA (5A), PSA/VPSA (13XHP), NaX (13X), LiLSX, ZSM-5, zeolites Ag-ZSM-5 and Ag400 modified with silver nanoparticles, as well as coconut and activated carbon from various manufacturers. The study is carried out on a setup for examining the sorption and separation characteristics of sorbents at various temperatures and pressures. As a result of the work, dynamic adsorption curves (Breakthroug curves) were obtained and the most optimal materials for the final traps of the MIKS were selected.
