Abstract

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.
