1引言抗坏血酸（Vc）对维持机体的正常生理功能．增强机体的抵抗力具有重要的意义、其测定方法多采用碘量法、荧光法、电化学法和光度法，但作为常规的分析，上述方法都不同程度的存在着操作过程繁琐、灵敏度低等缺点。化学发光法对Vc的测定近年来也有报道。作者发现Cu（Ⅲ）在
1 Introduction Ascorbic acid (Vc) to maintain the body’s normal physiological function. Enhance the body’s resistance is of great significance, and its determination of iodine method, fluorescence method, electrochemical method and luminosity method, but as a general analysis, the above methods have varying degrees of tedious operation, low sensitivity Disadvantages. Chemiluminescence assay Vc has also been reported in recent years. The authors found Cu (Ⅲ) in
