五羟色胺分子选择性电极研究

5-Hydroxytryptamine Molecule-selective Membrane Electrode

本文应用自己合成的联萘20-冠-6作为活性载体,进行了五羟色胺分子选择性电极研究。电极在10^(-5)～10^(-2)mol/L浓度范围内对五羟色胺具有稳定的线性响应,平均斜率为63mV/PC,检测下限为2.7×10^(-6)mol/L。

The 5-hydroxytryptamine molecule-selective electrode based on the molecule selective carrier, binaphthyl-20-crown-6, is reported. The linear response range is form 1. 0× 10^(-5) to 1. 0×10^(-2) mol/L with Nernstian so1pe of 63 mV/decade and detection limit of 2. 7× 10^(-6) mol/L.
