基于环糊精功能化介孔材料制备高选择性化学修饰电极
Preparation of Selective Modified Electrode Based on β-CD Functionalized Ordered Mesoporous Materials
摘要
Abstract
A novel modified carbon paste electrode (CD/SBA-15/CPE) with β-CD-functionalized SBA-15 mesoporous silica ( CD/SBA-l5) were fabricated and characterized. The recognition mechanism of nitrophe-nol, chloronitrobenzene and dihydroxybenzene isomers were studied at the modified electrode using cyclic vol-tammetry(CV) and differential pulse voltammetries ( DPV). The experiment results indicated that o-, m-, p-Nitrophenol, o-, p-Chloronitrobenzene and o-, p-Dihydroxybenzene isomers could be identified entirely at the CD/SBA-15/CPE, respectively. The detection sensivity of CD/SBA-15/CPE were increased resulting from the unique structure and chemical properties of SBA-15, the anodic or cathodic peak resolution of the isomers electrochemical reaction products was increased resulting from the superamolecular recognition of β-CD. The modified electrode might be applied in the practical field.关键词
