摘要:
基于混合煅烧法成功制备了磁性甘蔗皮碳化材料CoFe2O4@CSC,并通过XRD、TEM、SEM和VSM等对材料的晶相结构、表面形貌和磁性大小进行了表征. 将所制备的材料用于水体中4种菊酯类杀虫剂的磁固相萃取,实验结果表明,当材料使用量为40 mg、体系pH为7.0、平衡吸附时间10 min、选用乙腈为洗脱剂时,目标分析物的回收率最高可达到100.44%、99.74%、96.82%及99.22%,且材料循环使用6次后,萃取效果无明显下降. 环境水样的实际检测结果表明所建立方法具有良好的准确度与可靠性.
Abstract:
The magnetic sugarcane peel carbonized material CoFe2O4@CSC is successfully prepared on the basis of the hybrid calcination method. The crystal structure,surface morphology and magnetism of the material are characterized by XRD,TEM,SEM and VSM analysis. The results of magnetic solid phase extraction of four pyrethroid insecticides show the best conditions:the amount of material is 40 mg,the pH is 7.0,the equilibrium time is 10 min,and acetonitrile is selected as the eluent. The recovery rate can reach 100.44%,99.74%,96.82% and 99.22%. After the material recycles 6 times,the effect does not decrease significantly. The test of environmental water samples show that the established method has good accuracy and reliability.
