Abstract:
Results are presented of application of laser stepwise photoionization of atoms in combination with thermal atomization of matter in vacuum for direct determination of aluminum dissolved in sea and interstitial waters. Dry residue from evaporation of 40 ?l sea water was atomized in a crucible at 1800°C, and aluminum atoms in the beam thus formed were energized into Rydberg state in two steps by two tunable dye laser beams; the atoms were then ionized by an electric pulse and resulting ions were recorded by secondary emission electron multiplier (ion detector). Ionic signal dependence on sample vaporization time was studied. The procedure is suggested for separating out a selective signal in a single measurement. Dissolved aluminum concentrations in interstitial waters of the Indian Ocean and in waters of the river-sea zone were determined using preliminarily plotted calibration characteristics for aluminum solutions in deionized and sea waters. The minimum detectable Al concentration in seawater was 1 ?g/l that corresponds to 40 pg of Al in a sample.
