Sažetak The extraction and spectrophotometric determination of iron
(III) by 1-phenyl-2-methyl-3-hyd:roxy-4-pyridone (HX) are described.
At pH > 1.5 97°/o of the iron(III) can be extracted. A quantitative
reextraction of iron from the organic phase is possible with
an acid concentraicm higher than 1 M. The composition of the
iron(III)-HX complex formed tn the organic phase was investigated
spectrophotometrically, radiometrically and by a quantitative analysis
of the isolated species. In the aqueous phase iron(III) and HX
form three different complexes, depending on the initial iron(III)HX
concentration ratio and the pH of the solution. They are the
violet Fex2+, the orange-red Fex2+ and the orange-yellow FeX3.
The latter is identical with the complex found in the organic
phase.
