摘要

研究了一种基于聚苯胺/氧化钴的磷酸根修饰电极。该电极以玻碳电极为基底电极

以掺杂钴离子的聚苯胺为电极敏感膜。通过实验比较

得到对磷酸二氢根响应较好的钴离子掺杂浓度。制成的电极能斯特响应线性范围在10-1

0-4mol/L

斜率为-27.1 m V/dec

检测下限为9.3×10-5mol/L;电极具有较短的响应时间

很好的稳定性和重复性

对磷酸根的检测具有一定的研究意义。

Abstract

Study on a phosphate radical ion-selective modified electrode based on polyaniline / cobalt oxide

which is based on glassy carbon electrode as basal electrode and the cobalt ions-doped polyaniline as sensitive film.Concentration of cobalt ions-doped

which responses well to dihydrogen phosphate ion is obtained by test comparison. The electrode has a linear response in the concentration range of 10- 1

10- 4mol / L

with a slope of- 27. 1 m V / dec and a detection limit of 9. 3 × 10- 5mol / L;the electrode has short response time

good stability and repeatability

the method has a certain significance for the detection of phosphate radical.
