Представлены результаты исследования очистки трехкомпонентных растворов, содержащих ионы Cs+, Sr2+, Co2+, карбонатными и фосфатными сорбентами, полученными из природного доломита путем термической активации при 800 °С (Д-800), фосфатированием (ФД) и фосфатированием с последующей модификацией солями цирконила (ФД-Zr). Изучена селективность и эффективность сорбентов в трехкомпонентном растворе, в том числе при последовательном применении в несколько стадий. Установлено, что синтезированные сорбенты обладают различной селективностью к ионам Cs+, Sr2+, Co2+. Карбонатные и фосфатные сорбенты Д-800 и ФД в трехкомпонентной смеси селективно сорбируют ионы двухвалентных металлов Sr2+ и Co2+. ФД-Zr не проявляет селективности ни к одному из ионов. Ряды эффективности сорбции к изученным ионам для Д-800: Со > Sr, для сорбента ФД: Со > Sr » Cs и для ФД-Zr: Со > Sr > Cs. Установлено, что наиболее эффективная очистка трехкомпонентного раствора (степень извлечения ~98‒100 %) достигается путем комбинации карбонатных и фосфатных сорбентов на разных стадиях очистки. После комбинированной трехстадийной очистки раствора остаточные концентрации ионов Co2+ ниже предела обнаружения, а ионов Sr2+ и Cs+ составляют 0,02 и 0,31 мг/л соответственно.

This paper presents the results of a study on the purification of three-component solutions containing Cs+, Sr2+, and Co2+ ions using carbonate and phosphate sorbents obtained from natural dolomite by thermal activation at 800 °C (D-800), phosphating (PD), and phosphating followed by modification with zirconyl salts (PD-Zr). The selectivity and efficiency of sorbents in a three-component solution were studied, including sequential application in multiple stages. It was found that the synthesized sorbents exhibit varying selectivity for Cs+, Sr2+, and Co2+ ions. Carbonate and phosphate sorbents D-800 and PD selectively sorb divalent metal ions Sr2+ and Co2+ in a three-component mixture. PD-Zr exhibits no selectivity for any of the ions. The sorption efficiency for the studied ions is as follows: for D-800: Co > Sr, for PD: Co > Sr » Cs, and for PD-Zr: Co > Sr > Cs. It was found that the most effective purification of a three-component solution (recovery rate of ~98‒100 %) is achieved by combining carbonate and phosphate sorbents at different purification stages. After a combined three-stage purification of the solution, residual concentrations of Co2+ ions are below the detection limit, while those of Sr2+ and Cs+ ions are 0.02 and 0.31 mg/L, respectively.
