| 摘 要： | 采用木犀草素为pH值选择性试剂,石墨粉为导电基质,PVC为成膜材料,自制无毒无害的pH柔性膜电极(pH flexible electrode,pH/FE)。该电极有一个氧化峰,它的峰电位对2.00~9.00范围内的pH值有线性响应,并且具有弯曲度好、抗拉伸性强、溶胀性能稳定、准确度高,选择性好等性能。此电极有望作为柔性检测器件用于非平面介质表面液层pH值的测定。

| Abstract: | A non-toxic and harmless pH flexible membrane electrode was prepared with luteolin as pH selective reagent, graphite powder as conductive matrix, PVC as film-forming material. The electrode has an oxidation peak, its peak potential has a linear response to the pH in the range of 2.00 ~ 9.00, and it has good bending, strong tensile elongation, stable swelling performance, high accuracy, good selectivity. The electrode is expected to be used as a flexible detector for the determination of the pH of the liquid layer on the surface of nonplanar media. |

| Keywords: | luteolin flexible membrane electrode determination of pH squrare wave voltammetry |
