Summary: | Determination of cadmium in river water by sequential metal vapour elution analysis (column temperature; > 1500 K) with argon and hydrogen carrier gas and with atomic absorption spectrometric detection is described. The column is made of a molybdenum capillary tube (i.d. 1.22 mm) and the temperature is 1760 K. The cadmium vapor was separated from those of calcium, iron and sodium. The calibration graph was linear up to 15 mu/ml. Relative standard deviations of 0.8-4.3% were obtained in the range 1 to 15 mu/ml. Cadmium in spiked samples (river water) was determined. The results were in good agreement with the amount spiked. |
