摘要
本文利用水提取食品中乙二胺四乙酸二钠,加入还原剂使EDTA与铜形成络合物,利用液相色谱仪检测其络合物峰。加入三价铁,使EDTA-Cu络合物分解形成EDTA-Fe络合物,来确证EDTA的存在。该方法定性定量准确,测定过程快速。
In this paper, disodium edetate was extracted by water in food, the reducing agent was added to the EDTA forming complexes with copper, the use of liquid chromatography to detect the complex peak. Added to trivalent iron, and the EDTA-Cu complex formed by decomposition of EDTA-Fe complexes, and to validate the presence of EDTA. The method is accurate qualitative and quantitative determination process is fast.
