✦ Synopsis

How-injection atomic spectrometry with sorbent extraction preconcentration is applied to the simultaneous determination

of iron and i&III). Upon injection of a sample containing iron in both oxidation states, iron(III) is directly carried to the flame atomic absorption spectmmeter whereas the iro&I)-ferrozine complex formed in-line is temporarily retained on a C,,-modified silica column placed between the injection valve and spectrometer and is subsequently eluted with methanol.
