摘要：

The chemiluminescent reaction of lophine with H2O2 in alkaline solution has been investigated for use in determination of trace concentrations of metal ions and other inorganic species. The observed emission intensity is found to be a function of the reduction potential of the analyte. By varying reagent concentrations, it is possible to make dramatic changes in the relative sensitivity for a given analyte. Detection limits were found to be:[FORMULA OMMITED] Relative standard deviations are in the range of 2-5%. The intensity of the observed emission for a mixture of analytes is less than the sum of the signals for the separate analytes, is generally suppressed below the signal for either analyte alone. © 1979, American Chemical Society.
