✦ Synopsis

An atomic absorption

spectrometric method for the determination of sodium saccharin in commercially available mixtures of artificial sweeteners and pharmaceuticals by continuous precipitation with silver ion in a flow manifold is proposed. The silver saccharinate precipitate formed is retained on a filter, washed with diluted acetic acid and dissolved in ammonia for on-line atomic absorption determination of silver, the amount of which in the precipitate is proportional to that of saccharin in the sample. The proposed method allows the determination of sodium saccharin in the range 5-75 pug ml-' with a relative standard deviation of 2.7% at a rate of ca. 20 samples h-'. The method is very selective; other sweeteners do not interfere, but chloride must be absent.

## Abstract A new method for saccharin determination in liquid sweetener products was developed. The method is based on the precipitation reaction of Ag(I) ions with saccharin in aqueous medium (pH 3.0), using a flow injection analysis system with merging zones, the suspension was stabilized with 5
