摘要

以亚铁氰化铜（CuFC）、预处理蛭石（P-VT）和海藻酸钠（SA）为原料合成了新型复合水凝胶微球（CuFC- savt）。在pH 4.0和298.15 K条件下，复合微球对U（VI）的去除率为90.8%，明显优于单独使用CuFC的64.7%。动力学和等温线研究表明，CuFC-SAVT吸附U（VI）符合拟二级动力学模型和Freundlich等温线模型。CuFC-SAVT微球具有吸附性能好、易于分离、环境友好等优点。这些发现表明CuFC-SAVT在含铀废水处理中具有良好的实际应用潜力。

Adsorption properties and mechanism of copper ferrocyanide/vermiculite composite sodium alginate microspheres on U(VI) in aqueous solution

In this study, novel composite hydrogel microspheres (CuFC-SAVT) were synthesized by incorporating copper ferrocyanide (CuFC), pretreated vermiculite (P-VT), and sodium alginate (SA). The composite microspheres demonstrated superior U(VI) removal efficiency of 90.8% at pH 4.0 and 298.15 K, significantly outperforming the 64.7% achieved by CuFC alone. Kinetic and isotherm studies revealed that the U(VI) adsorption by CuFC-SAVT followed the pseudo-second-order kinetic model and Freundlich isotherm model. The CuFC-SAVT microspheres exhibited multiple advantages, including excellent adsorption performance, facile separation from solution, and environmental friendliness. These findings suggest that CuFC-SAVT holds promising potential for practical applications in uranium-containing wastewater treatment.
