| Abstract: | Ca,Fe,Zn,K,Na,Cu metal ions in the highland barley were determined by flame atomic absorption spectrometry,and the precision and accuracy tests are carried out. The results are as fouows：the contentof several metal ions are Ca 80. 011 mg / kg,Fe 77. 432 mg / kg,Zn 25. 645 mg / kg,K 40. 506 mg / kg,Na 12. 743mg / kg and Cu 3. 3648 mg / kg;their relative standard deviations are 0. 201% ,0. 463% ,0. 27% ,0. 364% ,0. 263% and 0. 059% respectively;recoveries are between 98. 21% ～ 102. 82% ,97. 17% ～ 100. 18% ,94. 76% ～ 99. 99% ,95. 32% ～ 100. 62% ,99. 61% ～ 99. 97% and 98. 87% ～ 100. 05% respectively. |
