| Abstract: | The suspension sampling technique was applied to flame atomic absorption spectrometry,and that was successfully used to directly determine calcium and iron in cola cao without digestion.The cola cao was made to suspension solution with suspension in agar jelly,and the test solution was injected into air-acetylene flame to determine calcium and iron by standard addition method.The average additional recoveries of calcium and iron were 96.3% and 95.2%,and RSD of calcium was less than 3.4%,that of iron was les... |
