Abstract

Laser-induced photoacoustic spectroscopy has been applied to the determination of chromate, uranyl, and Cr(VI) and Fe(II) ions as coloured complexes that were sorbed on ion-exchanger beads. A simple photoacoustic cell has been constructed; it consisted of a fused silica glass tube and an attached cylindrical piezoelectric transducer. A pulsed laser fight at 532 or 355 nm irradiated the ion-exchanger beads that had been collected in the glass tube of the cell. Since a sample material was effectively concentrated on the ion exchanger, the sensitivity was much higher than that in the corresponding photoacoustic spectrometry in a solution state. The lowest detection limit was 0.21 ng/ml Fe for Fe(II)-DPPS (4,7-diphenyl-1,10-phenanthrolinedisulphonate) complex sorbed on QAE-Sephadex gel. Analytical characteristics of the present method are described.
