THE STUDY OF LUMINOL-H2O2-IO4--S2- CHEMILUMINESCENCE SYSTEM AND ITS APPLICATION
摘要:
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.
