Abstract

In the present study, Zn-doped cobalt ferrite (CoFe1.9Zn0.1O4) magnetic nanoparticles were successfully synthesized via sol-gel method. The prepared materials were characterized using X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The apparent density and magnetic force of CoFe1.9Zn0.1O4 nanoparticles were determined. The results revealed that the prepared materials display an adequate density and considerable magnetic force. The gravimetric oil removal capability tests were also performed to investigate the oil absorption properties of CoFe1.9Zn0.1O4 nanoparticles using four types of oil samples (crude, diesel, gasoline and hydraulic oil) as water pollutant’s model. The oil removal capabilities of the prepared absorbent were found to be 13.72 ± 0.42-5.50 ± 0.53 g/g, 14.99 ± 0.95-8.86 ± 0.42 g/g, 18.23 ± 1.01-8.06 ± 1.26 g/g and 10.58 ± 0.49-5.24 ± 0.31 g/g for crude, diesel engine, gasoline engine and hydraulic oil, respectively. The results suggest that the prepared magnetic nanoparticles can be used as absorbent materials for removing oil spills from water surface.

锌掺杂钴铁氧体磁性纳米颗粒吸附去除水中溢油

本研究采用溶胶-凝胶法制备了掺杂锌的钴铁氧体(CoFe1.9Zn0.1O4)磁性纳米颗粒。采用x射线粉末衍射(XRD)、傅里叶变换红外光谱(FTIR)和扫描电镜(SEM)对制备的材料进行了表征。测定了CoFe1.9Zn0.1O4纳米粒子的表观密度和磁性。结果表明，制备的材料具有足够的密度和相当大的磁力。以原油、柴油、汽油、液压油4种油样为水污染物模型，进行了CoFe1.9Zn0.1O4纳米颗粒的重量脱油性能试验。所得吸附剂对原油、柴油、汽油机和液压油的除油能力分别为13.72±0.42 ~ 5.50±0.53 g/g、14.99±0.95 ~ 8.86±0.42 g/g、18.23±1.01 ~ 8.06±1.26 g/g和10.58±0.49 ~ 5.24±0.31 g/g。结果表明，制备的磁性纳米颗粒可作为去除水面溢油的吸附材料。
