| Abstract: | A method of detemination of micro amount kalium in food keep fresher by the standard of the atomic absorption spectrometry and directly showed curve of stadard add analytical results by atomic absorption work station was introduced. This method was suitable to rapid analysis of the laboratory in fatry. The results showed that the characteristic concentration was 10.7 μg/mL. The detection limit was 0. 567 μg/ml and recovery was 98.4% |
