| Abstract: | The determination of different valence chromium in sea water by graphite furnace atomic absorption spectrometry after using extract of Aliquat-336 is described. This method has better accuracy, and its variation coefficient is 6.0 %. The recovery is about 80% and characteristic amount is 6.3×10-14 g. This method can used be for the determination of sea water with different valence chromium. |
