摘要

Photothermal deflection spectroscopy was applied to the selective detection of iron(II) chelate with ferrozine by its sorption preconcentration 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 2.5 × 10−11 mol cm−2 at the plate from 15 μL of test solution (0.5 nM and 1.5 nM in solution, respectively), and the absolute detection limit is 8 fmol in the whole spot applied to a plate. Characteristics and features of photothermal deflection detection are discussed.
