Abstract
Periodate rapidly oxidizes the violet ferrous-2,4,6-tri-2-pyridyl- s-triazine complex to a colorless compound. This reaction serves as the basis for a simple procedure for the quantitative, colorimetric determination of periodate at the nanomolar level. Use of this assay was exemplified by a study of the course of oxidation of 1- to 2-μmolar samples of several representative carbohydrates.
