中文摘要: 该文采用一步法绿色合成β-环糊精(β-cyclodextrin, β-CD)多壁碳纳米管(multi-walled carbon nanotubes,MWCNT)磁性纳米材料(β-CD@MMWCNT),采用分散磁固相萃取技术,结合气相色谱建立同时检测蔬菜和水果中12种有机磷农药残留的检测方法。通过扫描电子显微镜(scanning electron microscope,SEM)、傅里叶变换红外光谱(Fourier transform infrared spectroscopy,FT-IR)和振动样品磁强计对β-CD@MMWCNT进行表征,结果表明,β-CD@MMWCNT成功合成,15 mg β-CD@MMWCNT净化提取液效果最佳。在最优试验条件下,12种有机磷农药残留在0.001~2.000 μg/mL范围内呈良好的线性关系,线性相关系数大于0.995,定量限为0.001 5~0.007 5 mg/kg。在0.01、0.05、0.10 mg/kg 3个加标水平下,回收率为68.64%~116.69%,相对标准偏差为1.06%~14.87%。综上,该文的合成β-CD@MMWCNT过程绿色环保,前处理简单、经济、安全,具有精密度和准确度高的优点,是一种很有前途的样品前处理净化材料。
Abstract:In this research, magnetic nanomaterial (β-CD@MMWCNT) was synthesized with β-cyclodextrin(β-CD) and multi-walled carbon nanotubes (MWCNT) by one-step green strategy. A method for the simultaneous detection of 12 organophosphorus pesticide residues in vegetables and fruits was developed by dispersive magnetic solid phase extraction combined with gas chromatography. β-CD@MMWCNT was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and vibrating sample magnetometry. The results showed that β-CD@MMWCNT was synthesized successfully, and the purification effect of 15 mg β-CD@MMWCNT was the best. Twelve organophosphorus pesticides had a good linearity in the range of 0.001-2.000 μg/mL and the correlation was greater than 0.995 under the optimal conditions. The quantification limit was between 0.001 5 mg/kg and 0.007 5 mg/kg. Under the three spiked levels of 0.01,0.05 mg/kg, and 0.10 mg/kg, the recoveries ranged from 68.64% to 116.69% with relative standard deviations of 1.06% to 14.87%. The synthesis of β-CD@MMWCNT by this method is green and environmentally friendly,and the pretreatment is simple, economical, and safe. It has the advantages of high precision and accuracy and is a promising sample pretreatment purification material.
