In this paper, beads-shaped hybrid sorbents composed of pectin and Prussian blue were prepared. Various ratios of pectin and Prussian blue in hybrid sorbents were tested. Obtained sorbents had high and roughly constant sorption capacity in a broad pH range (4-10), in which also the swelling index and stability of sorbents were satisfactory. The preliminary sorption studies proved that almost 100% of cesium removal efficiency may be achieved by using the proper sorbent dose. The sorption capacity of the hybrid sorbent with a 1:1 ratio of pectin to Prussian blue equaled q = 36.5 ± 0.8 mg/g (dose 3 g/L, pH = 6, temp. = 22 ± 1 °C, t = 24 h). The obtained results showed that the prepared hybrid pectin-based sorbents are promising for cesium ions removal.
本文制备了由果胶和普鲁士蓝组成的珠状混合吸附剂。测试了混合吸附剂中果胶和普鲁士蓝的不同比例。所获得的吸附剂在较宽的pH范围（4 - 10）内具有高且大致恒定的吸附容量，其溶胀指数和稳定性也令人满意。初步吸附研究证明，使用合适的吸附剂剂量可实现近100%的铯去除效率。果胶与普鲁士蓝比例为1:1的混合吸附剂的吸附容量为q = 36.5 ± 0.8 mg/g（剂量3 g/L，pH = 6，温度 = 22 ± 1 °C，时间t = 24 h）。所得结果表明，所制备的基于果胶的混合吸附剂在去除铯离子方面具有前景。
