摘要
将乙酰丙酮、环乙酮、氯仿按一定比例混合成萃取溶剂，可以在酸性介质中有效地萃取Ｆｅ^（３＋），然后将有机萃取液直接吸入火焰进行原子吸收分光光度法测定。实验证明，该方法有较好的精密度和准确度。
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.
