The sorption of Zr(IV) and Y(III) was examined using an iron-tin silicate (FeSnSi) composite prepared by the co-precipitation technique. The analytical tools that characterize prepared composite are FT-IR, SEM, EDX, XRD, and XRF. The effects of temperature, pH, ion concentrations, and shaking time are all considered in the sorption studies conducted on Zr(IV) and Y(III). The sorption of studied metal ions depends on pH, and the pseudo-2nd-order model governs the kinetics of reactions. Negative Gibbs energy values confirmed the excellent feasibility and spontaneity of the sorption process. Positive enthalpy values indicate that this process was endothermic. Positive entropy values demonstrated that the disorder between the solid and liquid phases was enhanced during adsorption. Freundlich and Langmuir models are used to study isotherms. The results of the binary system verify that Zr(IV) may be separated from the Zr-Y system at various pHs. According to the findings, the produced composite may effectively remove Zr(IV) and Y(III) from aqueous solutions. It may also be viable for purifying wastewater contaminated with these metal ions.

使用共沉淀技术制备的铁锡硅酸盐 (FeSnSi) 复合材料检查了 Zr(IV) 和 Y(III) 的吸附。表征所制备复合材料的分析工具有 FT-IR、SEM、EDX、XRD 和 XRF。对 Zr(IV) 和 Y(III) 进行的吸附研究中均考虑了温度、pH、离子浓度和振荡时间的影响。所研究的金属离子的吸附取决于 pH 值，伪二阶模型控制着反应动力学。负吉布斯能值证实了吸附过程的良好可行性和自发性。正的焓值表明该过程是吸热的。正熵值表明吸附过程中固相和液相之间的无序性增强。 Freundlich 和 Langmuir 模型用于研究等温线。二元系统的结果验证了Zr(IV)可以在不同pH值下从Zr-Y系统中分离出来。研究结果表明，所生产的复合材料可以有效地去除水溶液中的Zr(IV)和Y(III)。它也可能适用于净化被这些金属离子污染的废水。
