本文研究了多巴胺（ＤＡ）在铁氰酸钴膜（ＣＨＣＦ）修饰电极上的伏安行为，讨论了各种因素对ＤＡ伏安特性的影响，实验表明，该电极对ＤＡ的氧化有电催化作用。该电极可用于ＤＡ的测定，线性响应范围为４．０×１０－６～２．０×１０－４ｍｏｌ／Ｌ，电极寿命达３０天。
In this paper, the voltammetric behavior of dopamine (DA) on CHCF modified electrode was studied. The effects of various factors on the voltammetry of DA were discussed. The results showed that the electrode had an electrocatalytic effect on DA oxidation . The electrode can be used for the determination of DA, the linear response range of 4.0 × 10-6 ~ 2.0 × 10-4mol / L, electrode life of up to 30 days.
