Soluble manganese(IV); a new chemiluminescence reagent

The oxidations of twenty five organic and inorganic species, with solublised manganese(IV), were found to elicit analytically useful chemiluminescence with detection limits (3 x S/N) for Mn(II), Fe(II), morphine and codeine of 5 x 10(-8) M, 2.5 x 10(-7) M, 7.5 x 10(-8) M and 5 x 10(-8) M, respectively. Additionally, the corrected spectra from four different analytes gave wavelengths of maximum emission in the range from 733 nm up to 740 nm suggesting that all these chemiluminescence reactions shared a common emitting species.
