Abstract: 
1,10-Phenanthroline (phen) was tested as a complexing agent for on-line preconcentration of iron on RP-C18 material in a microcolumn with flow injection coupled with flame atomic absorption spectrometer (FI-FAAS). The on-line formed Fe(II)-phen complexes were adsorbed on the C18 sorbent material. Various parameters affecting the on-line Fe(II)-phen complex formation and its subsequent adsorption in the microcolumn as well as its elution into the nebulizer of AAS were optimized. A 2.5×10−3 mol/L phen in 2% ethanol was on-line mixed with aqueous sample solution acidified with 0.1% (v/v) HCl and allowed to flow through the microcolumn for 30 s. The adsorbed Fe(II)-phen complexes in the microcolumn were eluted with ethanol in 10 s into the nebulizer of AAS. Ascorbic acid (5×10−4 mol/L) was added to the sample solution for the reduction of Fe(III) to Fe(II). A good precision (RSD=1.1%, n=10), high enrichment factor (19) and sample throughput (90 h1) with detection limit (3σ) of 3 μg/L were obtained. The method was applied on standard reference materials (i.e. mussel and tomato leaves,) for iron determination and yielded results agreeing well with certified values.
