本文以几种碳—陶复合材料为电极材料制备离子敏感电极。这些电极对铜离子有较好的响应。其中以Ti和Al为添加剂的碳—陶复合材料制备的铜离子敏感电极分别在5×10~6～1×10~2mol/L和2.5×l0~6～1×10~(-2)mol/L呈能斯特响应,检测下限均为1×10~(-6)mol/L。这两种电极具有良好的稳定性和重现性。
In this paper, several carbon-ceramic composite electrode materials for the preparation of ion-sensitive electrode. These electrodes have a good response to copper ions. The copper ion sensitive electrodes prepared from carbon-ceramic composites with Ti and Al as additives were immersed in 5 × 10 ~ 6 ~ 1 × 10 ~ 2mol / L and 2.5 × 10 ~ 6 ~ 1 × 10 ~ (-2) mol / L Nernst response, the detection limit was 1 × 10 -6 mol / L. Both electrodes have good stability and reproducibility.
