Abstract
A continuous precipitation and filtration flow system for the separation of citric acid by precipitation with lead and indirect flame atomic absorption spectrometry is proposed. The precipitate is formed by injecting the lead solution into a carrier containing the sample and is subsequently retained on a filter. By using this reversed precipitation flow-injection configuration, citric acid was determined in the range 2–40 μg mL–1, with a relative standard deviation of 2.9% at a sampling frequency of 60 samples h–1. This method has been applied to the determination of citric acid in fruit juices, carbonated soft drinks and sweets.
