Application of photothermal deflection spectroscopy for the determination of iron(II) with ferrozine with sorption preconcentration on Silufol
Photothermal deflection spectroscopy was applied for selective detection of the intensely coloured iron(II) chelate with ferrozine on Silufol plates. The linearity range was 1 × 10-11 - 6 × 10-8 mol cm-2 of chelate at the plate surface, which corresponded to 1 × 10-9 - 4 × 10-6 M of chelate in solution. The limits of detection and quantification are 8 × 10-12 and 20 × 10-12 mol cm-2 at the plate from 15 μL of test solution (0.5 nM and 1.5 nM in solution, respectively), which corresponded to n × 10-18 mol absolute amounts of the chelate at the detection zone. © EDP Sciences/Societé Italiana di Fisica/Springer-Verlag 2008.
