制备了嵌入 Nafion-羧基多壁碳纳米管 (MWCNT) 的粉末微电极 (PME)，用于选择性、灵敏地测定磺酰胺类药物。优化了缓冲液pH、扫描速率等实验参数对电极响应的影响。在最佳条件下，所提出的PME可以大大提高测定灵敏度。在 Britton-Robison (BR) 缓冲溶液 (pH 2.0) 中，检测的线性响应范围为 1.0×10 -5
A powder microelectrode (PME), embedded with Nafion-carboxyl multiwalled carbon nanotubes (MWCNTs), was prepared for selective and sensitive determination of sulfonamides. The effects of experimental parameters on the response of electrode such as pH of buffer, scan rate were optimized. Under optimal conditions, the proposed PME can greatly improve the determination sensitivity. In a Britton-Robison (BR) buffer solution (pH 2.0), the linear response range for detection of 1.0×10 -5
