dc.description.abstract研制一种新型二氧化锰-酶修饰碳糊电极.应用直接电位法分别研究了磷酸盐底液的pH值、不同种类的粘合剂、二氧化锰修饰含量以及温度等各因素对该修饰电极测定H2O2和葡萄糖电位响应的影响.在优化实验条件(35℃,磷酸缓冲底液pH=7)下,葡萄糖检测的线性范围为2.0×10-5~5.2×10-3mol.L-1,灵敏度:36.12~34.62 mV/pG lucose,检测限:3.3×10-6mol.L-1.该电极具有良好的选择性、灵敏度、稳定性和重复性,大多数常见阴阳离子、甘露醇、丙三醇和脲不干扰测定.zh_CN
dc.description.abstractA novel carbon paste electrode(CPE) modified with MnO2 and glucose oxidase(GOx),is reported.Different factors,such as the effect of supporting electrolyte,pH of solutions,various paste glues,the amount of MnO2 and temperature,which may influence the determination of H2O2 and glucose were tested to optimize.Based on above,potentiometric determination of glucose was achieved in neutral solution and at 35 ℃,the electrode gave a response of 36.12~34.62 mV/pGlucose between 2.0×10-5mol·L-1 and 5.2×10-3 mol·L-1 with a detection limit of 3.3×10-6 mol·L-1.Moreover,this kind of the electrode had good stability and reproducibility.Most normal anion,cation,isotol,glycerin and amide will not interfere the determination of glucose.zh_CN
