Featured researches published by Herman D. Axelrod.


Analytica Chimica Acta | 1970

Fluorimetric determination of trace nitrates

Herman D. Axelrod; Joseph E. Bonelli; James P. Lodge

Abstract Nitrate is determined by reacting it with fluorescein in solutions of high sulfuric acid concentrations. Since fluorescein fluoresces and the reaction product does not, nitrate can be determined down to 0.01 μg ml-1 in the final reaction solution by measurement of the fluorescence suppression. The method is easy to use and has good reproducibility. Suggestions are offered to eliminate potential interfering ions.
