【 摘 要 】

Multi-wall carbon nanotube (MWNT)-modified glassy carbon electrodes (GCE) were prepared for simultaneous determination of rutin and quercetin. Microbial carbohydrates, �?-cyclosophorohexadecaose (�?-C16) and succinoglycan monomer M3 (M3) were doped into MWNTs to prepare a �?-C16-doped MWNT-modified GCE ((�?-C16 + MWNTs)/ GCE) and a M3-doped MWNT-modified GCE ((M3 + MWNTs)/GCE), respectively. The sensitivities of the (�?-C16 + MWNTs)/GCE to rutin and quercetin were 34.7 レA·レM^-1·cm^-2 and 18.3 レA·レM^-1·cm^-2, respectively, in a linear range of 2 ~ 8 レM at pH 7.2. The sensitivities of the (M3 + MWNTs)/GCE was 2.44 レA·レM^-1·cm^-2 for rutin and 7.19 レA·レM^-1·cm^-2 for quercetin without interference.
