| Abstract: | In order to study the content of micro-aluminum in grain,vigna minima was selected as the experimental material and fluorine selective electrode-direct reading method was adopted.The results indicated that the content of aluminum in vigna minima was 5.394 4 μg /g,the recovery was 101.81 %,the relative standard deviations(RSD) was 2.8 %(n=5),the linear range was 3.75~62.5 μg /g with the correlation coefficient 0.997 3 with satisfactory analytical results. |
