Co0.7Ni0.3Fe2O4纳米粒子作为Cu、Cr重金属吸附剂的结构、形态和磁性评价
随着铁氧体材料制造的发明,已经取得了越来越复杂的技术进步。在本评估中,使用共沉淀法来评估钴-镍铁氧体的结构、形态和磁性特性,用于Cu和Cr材料中的重金属吸附剂。用X射线衍射(XRD)和场发射扫描电子显微镜(FE-SEM)对合成的Co0.7Ni0.3Fe2O4钴镍铁氧体进行了结构和形貌分析,并用振动样品磁强计(VSM)测量了其室温磁滞回线。然后使用原子吸收光谱法测定金属含量(AAS)。XRD研究表明,在30.12°、35.57°、43.29°、53.71°和62.72°的2θ值下,(2 2 0)、(3 1 1)、(4 0 0)、。FE-SEM结果证实了铁氧体纳米颗粒的球形。发现Co0.7Ni0.3Fe2O4的平均粒径在80至120nm的范围内。Fe、Ni、Co和O元素的峰作为能量色散X射线(EDX)光谱研究了金属离子(Co:Ni)和铁与氧(Fe:O)的化学组成比。VSM结果的磁性能分别为34.46 emu/g、14.91 emu/g和671.58 Oe。相应地,AAS对Co0.7Ni0.3Fe2O4的去除率为99.86%,容量吸附量为11.23mg/L。
