摘要
本文用电化学方法制备了聚吡咯-水杨酸修饰电极;并进行了电化学行为的研究,经电化学处理该电极对水杨酸根具有选择性响应,响应线性范围在1.0×10^(-5)~1.0×10^(-3)mol/L之间.电极斜率为40mV/pC,该电极具有较好的稳定性,响应时间在180~300s之间;电极寿命可达60d.
Polypyrrole-salicylic acid modified electrode was prepared by electrochemical method. The electrode has selective response for salicylic acid group after electrochemical deposition. It shows a linear range of 1. 0×10-5-1.0×10-3 mol/L for salicylic acid and electrode slope of 40 mV/pC. The lifetime of the electrode was 60 d, and the response time was 180-300 s.
