对亚铁氰化钾掺杂的聚中性红膜修饰电极的制备及其电化学行为和Ｆｅ（ＣＮ）６４－在该电极上的催化作用进行了研究。结果表明，该修饰电极对Ｆｅ（ＣＮ）６４－存在较强的电催化作用，催化峰电流与Ｆｅ（ＣＮ）６４－的浓度在 １．０×１０－５～２．０×１０－３ ｍｏｌ／Ｌ范围内呈良好的线性关系，检测限可达５×１０－６ｍｏｌ／Ｌ
Preparation of poly (n-hexacyanoferrate) -doped poly-neutral red-film modified electrode and its electrochemical behavior and catalytic activity of Fe (CN) 64- on the electrode were studied. The results show that the modified electrode has a strong electrocatalytic effect on Fe (CN) 64-. The peak current and the concentration of Fe (CN) 64- are 1.0 × 10-5 ~ 2.0 × 10-3 mol / L range showed a good linear relationship, the detection limit of up to 5 × 10-6mol / L
