离子色谱法测定食品中防腐剂双乙酸钠的研究

The determination of preservative sodium diacetate in food by ion chromatography

本文采用离子色谱法测定食品中的双乙酸钠含量,实验结果表明,该方法可准确测定食品中的双乙酸钠且有很好的线性关系,相关系数大于99%,最低检出限为0.01mg/kg,加标回收率在90.0%～108.0%之间,可用于食品中双乙酸钠的检测。

A new method for the determination of sodium hydrogen in several food by ion chromatography was studied ,It is shown that the sodium hydrogen content was in a good linearity（r〉99%）.The lowest content sodium hydrogen determined was 0.01mg/kg .The recovery rate was 90.0%-108.0%,It can be applied to determine sodium hydrogen content in food
