| Abstract: | The effects of four surfactants and microemulsion were studied in the detection on trace manganses in food by flame atomic absorption spectrometry.The results showed that the absorption increased when one or two of surfactants and microemulsion were used.The microemulsion are the most effective.The absorption increased by 58%.A method of determination on trace manganese by means of atomic absorption spectrometry sensitized with microemulsion was established.At the same time,we also made a recovery experiment for trace manganese in food,The relative standard deviation is 2.90%-5.62%,and recovery is 97.0%-98.2%. |
