As a typical effective cesium ion removal method, this research presents a facile method of preparing potassium copper hexacyanoferrate on the surface of sludge created from refinery wastewater treatment (KCuHCFS). The IR, SEM–EDX, BET, and TGA were used to characterize the functionalized sludge KCuHCFS. On the adsorption process, the effects of Cs⁺ concentration, adsorbent dosage, γ-radiation, pH, time, and temperature were investigated. The KCuHCFS has a large surface area of 123 m² g⁻¹ and a mesoporous structure that is thermally and radiationally stable. Ion exchange between Cs⁺ and K⁺ is the most common mechanism for Cs⁺ elimination. KCuHCFS was successfully regenerated.

作为一种典型的有效去除铯离子的方法，本研究提出了一种在炼油厂废水处理产生的污泥 (KCuHCFS) 表面上制备六氰基高铁酸铜钾的简便方法。IR、SEM-EDX、BET 和 TGA 用于表征功能化污泥 KCuHCFS。研究了Cs ⁺浓度、吸附剂用量、γ-辐射、pH、时间和温度对吸附过程的影响。KCuHCFS 具有123 m ²  g ^-1的大表面积和热和辐射稳定的介孔结构。Cs ⁺和K ⁺之间的离子交换是最常见的Cs ⁺消除机制。KCuHCFS 成功再生。
