Abstract

Diphenyl-l, 10-phenanthroline, introduced in 1952 as a spectrophotometric reagent for iron by Smith, McCurdy and Diehl (1) , has proved useful and popular; some twenty papers (2) have now appeared detailing its application to the determination of iron in sea water, wine, serum, urine, various metals, and other materials. This reagent was given the common name Bathophenanthroline. The great sensitivity of the reagent is made peculiarly useful by virtue of the solubility of its red, ferrous derivative in isoamyl alcohol, for extraction of the red compound from water into the immiscible solvent provides a concentration method making possible the determination of iron in concentrations as low as 0.002 parts per million, and even more important, provides a method of removing the iron contaminants from the various reagents used in the analysis.
