基于钯水凝胶的电化学传感器选择性检测水合肼
Selective Determination of Hydrazine Hydrate on Palladium Hydrogels-modified Electrochemical Sensor
摘要
Abstract
Palladium hydrogel capped by β-cyclodextrins (Pdβ-CD) was prepared by a facile method with β-cyclodextrins and palladium(II) chloride,which were then modified onto the surface of gold electrode. The morphology and structure of the as-prepared palladium hydrogel were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), while the electrochemistry behaviors of gold electrode modified by Pdβ-CDwere investigated by cyclic voltammetry (CV) and differential pulse voltammetry(DPV). The results indicated the sensor had high electrochemistry response to hydrazine hydrate in the presence of K+,Na+,Mg2+,NH+4,Ni+2,Mn2+,Cl-,NO-3,SO2-4,PO3-4,HCOO-, C6H5O-3. Under the optimized conditions, the oxidized peak current showed linear relationship with the concentration of hydrazine hydrate in the concentration range of 25-950 μmol/L and the limit of detection (LOD) of 1.6 μmol/L(S/N=3).Owing to the facile preparation,high sensitivity and selectivity,the sensor has potential applications in determination of hydrazine hydrate in real water samples关键词
