糙米中总硒及水溶态和可交换态硒的测定(英文)

Determination of Total Selenium and Aqueous and Exchangeable Selenium in Crude Rice

用DAN荧光法测定硒含量的研究表明 ,施加硒肥的糙米中总硒的质量分数为 0 .0 75× 10 - 6 ,水溶态与可交换态硒的质量分数为 0 .0 2 0× 10 - 6 ,明显高于未施加硒肥的糙米中总硒的质量分数值 0 .0 4 5× 10 - 6 及水溶态与可交换态硒的质量分数值 0 .0 10× 10 - 6 .这说明对于缺硒地区的水稻培育 。

The total selenium and aqueous and exchangeable selenium was fluorometrically determined in two samples of crude rice;one had been fertilized with selenium and the other had not.The results show that the selenium level of the former sample(total selenium is (0.075×10^(-6));aqueous and exchangeable selenium is 0.020×10^(-6)) is higher than that of the latter(total selenium is 0.045×10^(-6);aqueous and exchangeable selenium is 0.010×10^(-6)).
