Determination of 26 Inorganic Elements in Soybeans by ICP-MS
In this paper,microwave digestion was used to pretreat soybeans,and the content of 26 elements in the digestion solution was determined by Inductively Coupled Plasma Mass Spectrometer(ICP-MS).The linearity,precision,accuracy and quality control samples of the method were verified.The results showed that the correlation coefficients of the standard curves of all elements were≥0.999 0,and the linear relationship was good.The detection limit was 0.000 583～0.453 000 mg·kg-1,the relative standard deviation was less than 5.513%,and the recoveries were 77%～113%.The method can accurately monitor the inorganic elements and in soybeans meet the daily detection requirements.
