Abstract

In this study, we combine magnetic solid phase extraction (MSPE), with the screen-printed carbon electrode (SPCE) modified by a molecular imprinted polymer (MIP) for sensitive and selective extraction and electrochemical determination of Rhodamine B in food samples. A magnetic solid phase extraction (MSPE) was carried out using magnetic poly(styrene-co-divinylbenzene) (PS-DVB) and magnetic nanoparticles (MNPs) synthetized on the surface of multiwalled carbon nanotubes (MWCNTs). An MIP was prepared on the surface of MWCNTs in the presence of titanium oxide nanoparticles (TiONPs) modifying the SPCE for the rapid electrochemical detection of Rhodamine B. The MIPs synthesis was optimized by varying the activated titanium oxide (TiO) and multiwalled carbon nanotubes (MWCNTs) amounts. The MSPE and electrochemical detection conditions were optimized as well. The present method exhibited good selectivity, high sensitivity, and good reproducibility towards the determination of Rhodamine B, making it a suitable method for the determination of Rhodamine B in food samples.

摘要

在这项研究中，我们将磁性固相萃取（MSPE）与通过分子印迹聚合物（MIP）修饰的丝网印刷碳电极（SPCE）相结合，用于食品样品中罗丹明 B 的灵敏和选择性萃取和电化学测定。通过在多壁碳纳米管（MWCNTs）表面合成磁性聚苯乙烯-共-二乙烯基苯（PS-DVB）和磁性纳米颗粒（MNPs）进行磁性固相萃取（MSPE）。在氧化钛纳米颗粒（TiONPs）的存在下在 MWCNTs 表面制备 MIP，以修饰 SPCE 用于罗丹明 B 的快速电化学检测。通过改变活性氧化钛（TiO）和多壁碳纳米管（MWCNTs）的量来优化 MIPs 的合成。还优化了 MSPE 和电化学检测条件。该方法对罗丹明 B 的测定表现出良好的选择性、高灵敏度和良好的重现性，使其成为食品样品中罗丹明 B 测定的合适方法。
