摘要: 合成了SBA-15有序多孔氧化硅材料并用β-CD对其进行了修饰,制备了功能化介孔修饰碳糊电极(CD-SBA15/CPE),利用循环伏安法(CV)、示差脉冲伏安法(DPV)等电化学技术,研究了修饰电极对硝基苯酚、硝基氯苯、苯二酚异构体的识别机理。研究表明:该修饰电极不仅能识别o-、m-、p-硝基苯酚、o-、p-硝基氯苯、o-、p-苯二酚异构体,且具有分辨率高、测定灵敏度高的特点。可望用于实际样品中同分异构体快速、灵敏和选择性检测。

Abstract: A novel modified carbon paste electrode (CD-SBA15/CPE) with β-CD-functionalized SBA-15 mesoporous silica(CD-SBA15) were fabricated and characterized. The recognition mechanism of Nitrophenol , Chloronitrobenzene and Dihydroxybenzene isomers have been studied at the modified electrode using cyclic voltammetry (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-SBA15/CPE, respectively. The detection sensivity of CD-SBA15/CPE were increased resulting from the unique structure and chemical properties of SBA15, the anodic or cathodic peak resolution of the isomers electrochencal reaction products was increased resulting from the superamolecular recognition of β-CD. The modified electrode might be applied in the practical field.
