| 摘 要： | This paper reports a new chemiluminescence system i.e.luminol-H_2O_2-IO_4~- catalyzed by sulphide ion(S~(2-)).Based on this catalysis,a newchemiluminescence(CL)method for the determination of trace S~(2-)is pro-posed.The detection limit is 0.2μg/LS~(2-),the linear dynamic range is 5μgto 100βμg/L S~(2-)and the variation coefficient at an sulphide concentrationof 100μg/L S~(2-)is 4.5%(n=10).The method has been satisfactory applied tothe determination of trace sulphide ion in water.

| Abstract: | This paper reports a new chemiluminescence system i.e.luminol-H2O2-IO4- catalyzed by sulphide ion(S2-).Based on this catalysis, a newchemiluminescence（CL）method for the determination of trace S2- is proposed.The detection limit is 0.2μg/L S2-, the linear dynamic range is 5μg to 100βμg/L S2- and the variation coefficient at an sulphide concentration of 10μg/L S2- is 4.5%(n=10).The method has been satisfactory applied to the determination of trace sulphide ion in water. |
