| Abstract: | The trace iron in acid solution (pH=1)can be extacted with the mixed-solvent of acetylacetone, cyclohexanone and chloroform.Then the organic extractant can be drawn in flame and directly determinated by atomic absorption spectrometry. The results are satisfactory in precision and accuracy. |
