通过调节溶剂热合成工艺制备了两种花状中空四氧化三钴(Co3 O4)微球,并采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、氮气吸附脱附仪、紫外-可见吸收光谱仪(UV-Vis)、红外光谱仪(FT-IR)等手段对 Co3 O4微球的形貌、尺寸、晶形结构、孔性能等进行了表征。结果表明,两种微球尺寸均为微米级, Co3 O4晶体结构为立方相尖晶石结构；两种微球的比表面积分别为26.77和2.51 m2/g。两种Co3 O4微球对污染物碱性品红的吸附性及解吸再利用性的研究结果显示,Co3 O4微球对碱性品红的最大饱和吸附量为2.7 mg/g,且重复再生循环6次后,吸附效率仍保持在60%以上。
In this paper,two kinds of flower-like Co3 O4 hollow microspheres were synthesized by solvothermal process.The scanning electron microscopy(SEM),X-ray diffraction(XRD),nitrogen adsorption instrument, UV-visible diffuse reflectance spectroscopy (UV-Vis),infrared spectrometer(FT-IR)were used to characterize the size,crystal structure,pore properties of the Co3 O4 hollow microspheres.The results showed that the two kinds of Co3 O4 microspheres are micron-sized,cubic phase spinel structure,and the specific surface area were 26.77 and 2.51 m2/g,respectively.The adsorption and regeneration properties of the two kinds of Co3 O4 mi-crospheres to basic fuchsin were compared.The study results showed that the two kinds of Co3 O4 microspheres exhibited high adsorption capacities and excellent regeneration ability to basic fuchsin.The solid-phase adsor-bate concentration at equilibrium was 2.7 mg/g.After recycling 6 times,the adsorption efficiency was still above 60%.
