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
