对掺磷钼杂多酸聚吡咯电极的聚合、伏安行为，及其对多巴胺的电催化效应进行了研究。该膜电极性能稳定，多巴胺浓度在５×１０－５ｍｏｌ／Ｌ～１０－２ｍｏｌ／Ｌ成线性关系，检测限为８．０×１０－６ｍｏｌ／Ｌ，用于多巴胺针剂中多巴胺（ＤＡ）的含量测定获得满意的结果。
The polymerization and voltammetric behavior of the polypyrrole electrode doped with phosphomolybdic molybdenum and its electrocatalytic effect on dopamine were studied. The membrane electrode performance is stable, dopamine concentration in 5 × 10-5mol / L ~ 10-2mol / L has a linear relationship, the detection limit of 8.0 × 10-6mol / L, for dopamine injection dopamine (DA) content Determination of satisfactory results.
