一种可用于检测食品中亚硝酸盐的聚2,6-二氨基吡啶-铁氰化镍修饰电极的制备方法
Abstract:
本发明涉及一种可用于检测食品中亚硝酸盐的聚2,6‑二氨基吡啶‑铁氰化镍修饰电极的制备方法。包括以下步骤：聚2,6‑二氨基吡啶‑铁氰化镍修饰电极的制备、聚2,6‑二氨基吡啶‑铁氰化镍修饰电极对亚硝酸盐的检测。本发明的有益效果是：聚2,6‑二氨基吡啶‑铁氰化镍修饰电极的制备方法简单,对亚硝酸盐的检测响应较快，聚2,6‑二氨基吡啶不仅可用于掺杂具有电催化性能的铁氰化镍，还可以对待检测的亚硝酸盐产生较强的静电吸引，使亚硝酸盐在聚2,6‑二氨基吡啶的表面发生预浓集而提高检测灵敏度。
Abstract(English):

The invention relates to a preparation method of a poly 2,6-diaminopyridine-nickel ferricyanide modified electrode capable of detecting nitrite in food. The preparation method comprises the followingsteps: preparing the poly 2,6-diaminopyridine-nickel ferricyanide modified electrode and detecting nitrite with the poly 2,6-diaminopyridine-nickel ferricyanide modified electrode. The preparation method of the poly 2,6-diaminopyridine-nickel ferricyanide modified electrode has the beneficial effects that the preparation method is simple, response to nitrite detection is faster, poly 2,6-diaminopyridine not only can be used for doping nickel ferricyanide with electro-catalytic property, but also can produce stronger electrostatic attraction for to-be-detected nitrite, so that nitrite is pre-concentrated on the surface of poly 2,6-diaminopyridine, and detection sensitivity is improved.
