Abstract

(1-x)ZnO–xNiO nanocomposites (where x = 0.05, 0.10, 0.15 and 0.20) have been successfully synthesized using a mechanical mixing approach. Structural phase, morphological, and elemental composition analysis have been carried out using X-ray diffraction, scanning electron microscope, EDX, and XPS analysis. The systematic batch mode adsorption studies were carried out to evaluate the optimized adsorption behavior of synthesized nanocomposites (pH = 6; contact time = 90 min and adsorption dose = 0.5 g/L). Kinetic studies revealed that the prepared nanocomposite (0.80ZnO0.20NiO) successfully adsorbs U(VI) through a chemisorption nature with the maximum Langmuir capacity (~ 151.20 mg/g). The results demonstrated that the prepared 0.80ZnO0.20NiO can be used as a packaging material for column units in water purifiers.

ZnO-NiO 复合材料的合成与表征:高效的六(U)元素清除剂
(采用机械混合方法成功合成了 (1-x)ZnO-xNiO 纳米复合材料(其中 x = 0.05、0.10、0.15 和 0.20)。利用 X 射线衍射、扫描电子显微镜、EDX 和 XPS 分析进行了结构相、形态和元素组成分析。为了评估合成纳米复合材料的优化吸附行为(pH = 6;接触时间 = 90 分钟;吸附剂量 = 0.5 克/升),进行了系统的批次模式吸附研究。动力学研究表明,制备的纳米复合材料(0.80ZnO0.20NiO)通过化学吸附成功地吸附了 U(VI),其朗姆吸附容量最大(~ 151.20 mg/g)。结果表明,制备的 0.80ZnO0.20NiO 可用作净水器中柱单元的包装材料。
