Chemiluminescence of Lumindnol-KIO4-Fe(1, 10-phen)32+ System and Its Application

    Abstract
  • This paper reports a new complex chemiluminescence,i.e.luminol-IO4-catalyzed by Fe(1,10-phenanthroline)32+ complex. Based on this catalysis a new chemiluminescence method for the determination of trace Fe(Ⅱ) is proposed. The detection limit is 1.6×10-7g/L Fe(Ⅱ),the linear dynamic range is 1×10-5-1×10-3g/L Fe(Ⅱ) and the variation coefficient at an iron concentration of 2×10-4g/L Fe(Ⅱ) is 3.5% (n=10).This method has ho satisfactorily applied to the determination of trace iron ion in precipitated BaSO4 samples.
