摘　　要：建立测定葡萄酒中甜蜜素的离子色谱法(IC法)。进行IC法与气色谱法(GC法)比对实验,并对2种方法的实验数据进行统计学分析。结果表明,在选定实验条件下,IC法和GC法的相关系数r分别为0.999 6和0.999 9,平均回收率分别为95.5%,93.8%,相对标准偏差分别为1.38%,2.27%。两种方法检测结果之间无显著性差异。IC法具有简便、快速、准确等特点,适用于葡萄酒中甜蜜素的测定。To develope a method of determination of sodium cyclamate in wine by ion chromatography.The comparison experiment of GC and IC was performed,the experimental data were statistically analyzed. Results showed that under the certain experimental condition,the correlation efficient（ r） were0. 999 6 and 0. 999 9,respectively. Average recoveries were 95. 5% and 93. 8%,RSD were 1. 38% and2. 27%. The results of two methods was not significantly different. IC was simple,rapid and accurate,Which was suitable for determination of sodium cyclamate in wine.
