Spectrophotometric Determination of Trace Iron in Solution
LESSON PLAN SPECTRONIC 200 Visible SpectrophotometerSpectrophotometric Determination of Trace iron in SolutionMeasure the concentration of iron using a calibration curveThe chemical structure and numbering scheme for 1,10-phenanthroline is shown in Figure The ability to measure the concentration of iron in aqueous solutions in a quick and efficient way is important to many industries. Manufacturing industries where metal parts need to be cleaned may need to determine the level of iron in their waste streams for environmental compliance. Governments at all levels have an interest in testing wastewater, natural waters, and drinking waters to determine iron content to ensure compliance with the law and to ensure the safety of the water supply for wildlife and the human , modern laboratories may perform iron content analysis by atomic emission spectroscopy in an inductively coupled plasma (ICP) spectrometer.
Flame atomic absorption spectrometry also can be used, but iron solutions are notorious for clogging the burner with iron oxide when the concentration exceeds a certain level. Both of these techniques require a significant investment in instrumentation and a …
