一种抗坏血酸检测用的显色剂及其应用
摘要：
本发明涉及一种显色剂及其制备方法和应用。所述显色剂由羟基氧化钴纳米片混悬液与3,3',5,5'‑四甲基联苯胺水溶液混合制得；其中所述羟基氧化钴纳米片与所述3,3',5,5'‑四甲基联苯胺的摩尔比为2:1。所述显色剂用于检测抗坏血酸，灵敏度较高，检测限较低。
摘要（英）：

The invention relates to a color developing agent and a preparation method and an application thereof. The color developing agent is prepared by mixing a CoOOH nano sheet suspension with 3, 3', 5,5'-tetramethyl benzidine water solution according to the molar ratio CoOOH nano sheets to 3, 3', 5,5'-tetramethyl benzidine of 2:1. The color developing agent is used for detecting ascorbic acid, and has high sensitivity and low detection limit.
