Abstract

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 x 10(-11)-6 x 10(-8) mol cm(-2) of chelate at the plate surface, which corresponded to 1 x 10(-9)-4 x 10(-6) M of chelate in solution. The limits of detection and quantification are 8 x 10(-12) and 2.5 x 10(-11) mol cm(-2) at the plate from 15 mu L 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.
