Abstract

An intracavity laser spectroscopic method and the necessary instrumentation are described for the direct determination of trace amounts of iodine in water and in biological media. Minimal sample preparation is required for the laser probing of vapours over the surface of the heated liquid in a closed cell. This laser method is also applied to measurements of ultra-low barium contents in water by sample evaporation in a standard graphite furnace electrothermal atomizer. Detection limits of 0.015 mg l–1 and 0.2 ng l–1 were obtained for iodine and barium, respectively, which are 2–3 orders of magnitude lower than those obtained using a pulsed dye laser. The precision of the method was 10% for the lowest concentrations measured. The procedure is comparatively simple, quick and inexpensive.
