Abstract
The present paper reports a new chemiluminescence system, i.e, acetone-H2O2−C10−, which can be catalyzed by iodide ion (I−). Based on this catalysis, a new chemiluminescence method for the determination of trace iodide ion is proposed. the optimum conditions are reported in this note. the detection limit is 2 × 10−11 g/ml I−, the linear dynamic range is 4 × 10−10 g/ml to 3 × 10−7 g/ml I−, and the variation coefficient at an iodide concentration of 5 × 10−9 g/ml I− (n=10) is 4.6%. the method has been satisfactorily applied to the determination of trace iodide ion in water.
