[Photometric analysis of sodium and cesium iodides in the air of the work area]. / Fotometricheskoe opredelenie iodidov natriia i tseziia v vozdukhe rabochei zony.

The contributors propose a photometric technique for detecting sodium and caesium iodides in the working zone air. The technique is based on the oxidation of I-ions with bromine water, interacting of the educed iodine and redundant potassium iodide with concomitant formation of complex I3- ions, followed by 350-365 mm photometric measurements of the product. Air sample taking is performed by condensating on AFA--VP filtres. The lower limit of I-ions content measurements is 5 micrograms. The measurement range for sodium and caesium iodides is 0.2-50 mg/m3. Data is provided for the reproduction of the technique which can be used both in special laboratory and industrial conditions.
