Improved Spectrophotometric Determination of Total Iron and Iron(III) with o-Hydroxyhydroquinonephthalein and Their Characterization

Simultaneous and fractional determination of iron(II) and iron(III) was accomplished with o-hydroxyhydroquinonephthalein (QP) in the presence of poly (N-vinyl pyrrolidone). In the determination of total iron (iron(II)+iron(III)), Beer's law was obeyed in the range of 0.02-0.67 μg·ml−1, with an...
