Abstract

Herein, MnFe2O4 binary oxides, including various percentages of Fe3O4 were synthesized using the chemical co-precipitation method. In order to determine the physicochemical properties, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (SEM-EDX) analyses were used. Adsorbent dosage, pH of the solution, contact time, and adsorbate concentration were optimized during the adsorption process. It was found that the Langmuir isotherm model is the best kinetic model for adsorption. Finally, the mean adsorption energy, reproducibility, and spontaneity of the adsorbent were also estimated, which showed that the physical adsorption mechanism is dominant.

化学共沉淀法合成铁酸锰纳米颗粒作为铅的磁性吸附剂

本文采用化学共沉淀法合成了含不同比例Fe3O4的MnFe2O4二元氧化物。采用傅里叶变换红外光谱(FT-IR)、x射线衍射(XRD)和能量色散x射线光谱(SEM-EDX)分析确定了其物理化学性质。在吸附过程中，对吸附剂用量、溶液pH、接触时间、吸附质浓度进行了优化。Langmuir等温线模型是吸附的最佳动力学模型。最后，对吸附剂的平均吸附能、再现性和自发性进行了估计，表明物理吸附机制占主导地位。
