| Abstract: | The mineral element germanium in rice and by-product were analyzed. Under the optimized experimental conditions, the regression equation of the standard curve is A=0. 012 36 C＋0. 030 39 with the correlation coefficient r=0. 999 6. The linear range of determination is 0-7.2 μg/mL. The recovery is 98. 5%-106. 5% and the relative standard deviation is 1.57%. The results show that the content of germanium in rice, rice bran, rice straw, rice husk, rice leaf is 0. 738 2 μg/g, 3. 971 3 μg/g, 7. 597 9 μg/g, 13. 644 0μg/g and 14. 906 1μg/g, respectively. |
