摘要：

建立了离子色谱测定红酒中高氯酸盐的分析方法。以4种葡萄酒为典型样品，测定了其中的高氯酸盐含量。使用Metrosep A Supp5阴离子分析柱（150 mm×4.0 mm）进行分离，柱温为40℃，流动相为1.0 mmol/L碳酸钠水溶液-丙酮（85：15，v/v），流速为0.8 mL/min。结果表明，高氯酸盐在0.1~10 mg/L内具有良好的线性关系，相关系数为0.9998，方法回收率大于86.0%，相对标准偏差小于2.6%。该方法前处理方便快捷、检测灵敏度高，可满足红酒中高氯酸盐含量的测定。

Abstract:

An ion chromatographic method was developed for the determination of perchlorate in wine. The content of perchlorate in four kinds of wine was determined. Metrosep A Supp5 column (150 mm×4.0 mm) was used for the separation with the eluent of 1.0 mmol/L Na2CO3-acetone (85 : 15, v/v) at the flow rate of 0.8 mL/min, and the column temperature was 40℃. Perchlorate had good linearity in the range of 0.1-10.0 mg/L. The recoveries of the method were more than 86.0%, and the relative standard deviations were less than 2.6%. The method is simple and rapid, and can be used for the determination of perchlorate in wine.

Key words: ion chromatography (IC), perchlorate, wine
