✦ Synopsis

A simple flow-injection system with chemiluminescent detection for selective determination of sulphite is described. The light accompanying the reaction between sodium carbonate and copp&II) mixture solution with sulphite is detected. The concentration of sulphite is proportional to the chemiluminescence intensity in the range of 1.0 X 10e6-5 X 10m4 mol 1-l. The limit of detection is 5 X lo-' mol 1-l and the relative standard deviation is 4.6% for the 5 X 10e6 mol 1-l sulphik solution in nine repeated measurements. This method has been successfully applied to the determination of sulphite in wines. The possible reaction mechanism is also discussed.
