Abstract

The application of 1-(4-tolyl)-2-methyl-3-hydroxy-4-pyridone
(HY) to the extraction and spectrophotometric determination of
iron (III) are described.
In the aqueous phase iron (III) and HY form two different
complexes; FeY2+ and FeY2+, depending on the iron-HY concentration
ratio and the pH of the solution. It was found that only
the FeY2+ complex is extracted into chloroform.
