Abstract:

A method has been developed for the determination of chlorite, chlorate and perchlorate in carbonated beverage
by using ion-chromatography-electrospray tandem mass spectrometry (IC-ESI-MS) in a negative ESI mode. Chlorite
chlorate and perchlorate were separated on a high-capacity, hydroxide-selective column by gradient elution with KOH eluent
generated from an eluent generator cartridge (EGC). The linear range was 1–200 ng/mL with a linear correlation coefficient
of 0.997. The quantitation limits for chlorite, chlorate and perchlorate were 1.5, 1.0 μg/L and 0.6 μg/L, respectively. The
recovery rates from spiked standard samples were in the range of 79%–104% with RSD in the range of 0.54%–4.49%
(n = 6). This method proved to be simple, quick, sensitive and precise. It can be applied widely and suitable for simultaneous
determination of chlorite chlorate and perchlorate in carbonated beverage.

Key words: IC-MS, carbonated beverage, chlorite, chlorate, perchlorate
