A new catalytic spectrophotometric method for the determination of trace Mn has been developed. The theory of method is discussed. Optimum conditions for the determination of Mn have been established. The sensitivity of method is 6.4 times higher than conventional catalytic spectrometric method. This method has been applied to the determination of Mn in cereal samples.
