Hybrid sorbents composed of various ratios of Prussian blue (PB) and pectin were tested for their ability to remove cesium ions in batch and column mode. The maximum sorption capacity calculated from Langmuir isotherms was obtained for a sorbent with 50% PB additive (63.8 ± 1.7 mg g⁻¹). The sorption kinetics studies performed at 12°C, 22°C, and 32°C and the equilibrium studies indicate physical sorption. The good sorption kinetics and the bead form of the proposed sorbents allowed column tests to be performed. Using 3 g of sorbent (50% PB), 870 mL of solution with an initial cesium content of 120 mg L⁻¹ was purified to <2.4 mg L⁻¹ (most of the eluate contained cesium at a level of 0.1 mg L⁻¹). The effect of NaCl, KCl MgCl₂, and CaCl₂ at different concentrations on the sorption of cesium ions was also examined. The results indicated that the sorbent was also effective in a strongly saline environment, as well as in substitute ocean water and real Baltic seawater. The proposed sorbent enables safe, long-term storage of radioactive item in an air-dry, dust free state and in the smallest volume of material of high sorption capacity. This type of treatment is crucial for the disposal of radioactive waste whose activity can only be reduced by decay. Therefore, our hybrid sorbent is a promising material for the removal of (radioactive) cesium ions using either continuous or batch processes from waste aqueous solutions from a variety of sources, even those containing significant amounts of other ions.

测试了由不同比例的普鲁士蓝 (PB) 和果胶组成的混合吸附剂在批次和柱模式下去除铯离子的能力。^{对于具有 50% PB 添加剂 (63.8 ± 1.7 mg g -1} )的吸附剂，获得了从 Langmuir 等温线计算的最大吸附容量。在 12°C、22°C 和 32°C 下进行的吸附动力学研究和平衡研究表明物理吸附。所提出的吸附剂的良好吸附动力学和珠粒形式允许进行柱测试。使用 3 g 吸附剂 (50% PB)，将 870 mL 初始铯含量为 120 mg L ^-1的溶液纯化至 <2.4 mg L ^-1（大部分洗脱液中的铯含量为 0.1 mg L ^{- 1} )。NaCl、KCl MgCl 的影响₂、不同浓度的CaCl ₂对铯离子的吸附作用也进行了考察。结果表明，该吸附剂在强盐碱环境以及替代海水和真正的波罗的海海水中也有效。所提出的吸附剂能够以空气干燥、无尘状态和以最小体积的高吸附容量材料安全、长期储存放射性物品。这种类型的处理对于放射性废物的处置至关重要，放射性废物的活性只能通过衰变来降低。因此，我们的混合吸附剂是一种很有前途的材料，可以使用连续或间歇工艺从各种来源的废水溶液中去除（放射性）铯离子，即使是那些含有大量其他离子的废水溶液。
