| Abstract: | The method for analysis of six trace elements（Cu,Fe,Zn,Ca,Mg and K）in black-skinned peanut was established by flame atomic absorption spectrometry combining with high-pressure closed-vessel digestion system and mixture solution of nitric acid as digestion solution.LaCl3 and CsCl were used as releasing agent to eliminate chemical interference to determination of calcium,magnesium and potassium,respectively.The relatively standard deviation was 0.30%—2.38%,and the recovery was from 95.0% to 110.0%.Some elements essential to human such as Cu,Fe,Zn,Ca,Mg and K in black-skinned peanut were relatively abundant.The contents of Cu,Fe,Ca,Mg and K in peanut skins were higher than that in kernels.The levels of six elements contents in black-skinned peanut were compared with that of other two local peanuts. |
